The NH SDC JUPITER Raw Data Archive
========================================================================
Introduction
============
This document provides an overview of this dataset of
the New Horizons (NH)
SDC JUPITER Raw
Data Archive, including a general listing of the dataset contents.
This dataset contains flight data leading up to and including the
Jupiter encounter
for the
Student Dust Counter
instrument of the New Horizons mission. These data were collected
from
2007-01-01T00:00:00
up to
2007-06-27T00:00:00
. See the Mission catalog file NH.CAT in the /CATALOG/ directory for a
description of the New Horizons mission.
Required Reading
================
The information contained in all documents included with, and
referenced in, this archive, is an integral part of this archive.
Specifically, the information contained in the SOC Instrument
Interface Control Document (ICD), and in the documents submitted
for publication in Space Science Reviews in 2007, is crucial to
understanding the data in this archive. As such, the producers
of this archive have included the best possible version of these
documents with this archive.
* SOC Instrument Interface Control Document (AKA the ICD)
The ICD specifies the interfaces between the New Horizons
Science Operations Center (SOC) and the instrument pipeline, which
process data from raw to calibrated units. The ICD's purpose is to
define the various aspects of the interfaces in sufficient detail
to establish a clear understanding between the SOC and the
instrument team to allow for a parallel pipeline development.
This file is located in the /DOCUMENT/ directory of this
data set and its filename is SOC_INST_ICD.DOC. Other versions
of this file in different formats are listed in SOC_INST_ICD.LBL.
In addition to mission-wide information, the ICD contains an entire
section devoted to the details of the SDC instrument. The
most important aids provided to the user of this archive by the ICD
are
* Descriptions of the data files that comprise the
data portion of this archive.
* Descriptions of the calibration methodology of the
SDC instrument data.
* Overview descriptions of the SDC instrument theory
and operations.
* References to more detailed documentation.
* SDC Space Science Reviews documents (AKA SSR paper(s))
Scientific papers describing the New Horizons mission,
spacecraft, mission design, payload and instruments were submitted
to the publication Space Science Reviews in 2007 after the Jupiter
encounter; refer to the references catalog for full citations.
These files are located in the /DOCUMENT/ directory of this
data set.
The filename of the instrument SSR paper is SDC_SSR.PDF;
other versions of this file are listed in SDC_SSR.LBL.
The filename of the payload SSR paper is PAYLOAD_SSR.PDF;
other versions of this file are listed in PAYLOAD_SSR.LBL.
The SDC instrument and payload overview SSR papers, I.E.
Horanyi, M., et al., 2008 [HORANYIETAL2007]
and
Weaver, H.A., et al., 2008 [WEAVERETAL2007],
provide details of the SDC theory, design, ground testing
and calibration, operational considerations, and post-launch
checkout results.
Because of time and copyright restrictions, the SSR papers could not
be included in this archive in their peer-reviewed and published form.
However, Space Science Reviews did agree to allowing the submitted
versions of these papers to be included in this archive. This has
been done with the initial version of this archive as a convenience
to the user of this archive. However, it should be noted that
(1) NASA archive procedures do not guarantee that archive
documentation will remain with archive data as archives are
migrated to newer media. Therefore, it may in the future be
up to the user of this archive to use the references provided
to obtain the documents.
(2) There will be changes made to the submitted papers before they
are published. Where any differences exist between the
submitted versions of these documents in this archive and the
final published versions, the final published versions should
be considered authoritative, and it is up to the user of this
archive to assess if any such differences will affect their use
of this archive.
Other important documents are available in the following files:
NH Trajectory table:
/DOCUMENT/NH_TRAJECTORY.*
SDC Field Of View definitions:
/DOCUMENT/NH_FOV.*
/DOCUMENT/NH_SDC_V###_TI.TXT
Further pointers to important documents for this data set
are available in the following files:
/CATALOG/CATINFO.TXT
/CALIB/CALINFO.TXT
/DOCUMENT/DOCINFO.TXT
All reasonable efforts have been made to include the documents in
multiple formats in the document portion of this archive. Where
that was not possible due to copyright restrictions, references
to the documents have been included in this archive, and it is
up to the user of this archive to obtain a copy of such documents.
The original format of the ICD was MSWORD, and the original format
of the SSR papers was PDF, as noted above. All other formats may
show some loss in quality, especially in images, so the user is
encouraged to get the best possible version of these documents.
Volume Format
=============
This volume has been formatted according to the PDS Standards
Version 3.7.
This volume does not contain any Extended Attribute Records (XAR).
Thus, some VAX/VMS users may have problems accessing files on this
volume.
File Formats
============
All text documents and other meta information files such as
descriptions, PDS object definitions and detached PDS labels are
stream format files, with a carriage return (ASCII 13) and a line
feed character (ASCII 10) at the end of the record. This allows
the files to be read by most current operating systems.
Volume Contents
===============
Files on this volume are organized into a set of subdirectories
below the top-level directory. The following table shows the general
structure and content of these directories, but does not exhaustively
list every file in each directory. See the *INFO.TXT files in each
top-level sub-directory for specific information about the files
under that directory.
In this table, directory names are surrounded by forward slashes (/),
and the top-level of the volume is indicated by a single forward slash.

Filenames and Product IDs
=========================
The filenames of data files and the Product IDs of observations adhere
to a common convention e.g.
ALI_0123456789_0X0AB_ENG_1.FIT
^^^ ^^^^^^^^^^ ^^^^^ ^^^ ^\__/
| | | | | ^^
| | | | | |
| | | | | +--File type (includes dot)
| | | | | - .FIT for FITS file
| | | | | - .LBL for PDS label
| | | | | - not part of Product ID
| | | | |
| | | | +-- Version number from the SOC
| | | | (Science Operations Center)
| | | |
| | | +--ENG for Raw data *
| | | SCI for Calibrated data *
| | |
| | +--Application ID (ApID) of the telemetry data
| | packet from which the data come
| |
| +--Spacecraft Receipt Mission Elapsed Time (SCRMET)
|
+--Instrument/observation designator
Note that, depending on the observation, the SCRMET in the data
filename and in the Product ID may be similar to the Mission Elapsed Time
(MET) of the actual observation acquisition, but should not be used as an
analog for the acquisition time. The SCRMET is the time that the data
are transferred from the instrument to spacecraft memory and is therefore
not a reliable indicator of the actual observation time. The PDS label
and the index tables are better sources to use for the actual timing of
any observation. The specific keywords and index table column names for
which to look are
* START_TIME
* STOP_TIME
* SPACECRAFT_CLOCK_START_COUNT
* SPACECRAFT_CLOCK_STOP_COUNT
Data directory naming convention
================================
All of the data files in this dataset are under, but not in, the top-level
/DATA/ directory. Sub-directories, based on the SCRMET (see above) of the
top-level /DATA/ directory have been provided to increase the granularity of
data storage locations which in turn keeps there from being too many data
files in any one directory. The granularity implemented is one sub-directory
per 10,000 counts of the SCRMET (see Filenames and Product IDs section above).
The subdirectory names on this volume reflect that granularity. These
names are of the form
YYYYMMDD_SCRMET/
where SCRMET is a grouping of the first six digits of the ten-digit SCRMET
count, and YYYY, MM, and DD are the year, month and day of the first
possible SCRMET corresponding to that six-digit SCRMET prefix. Any data file
will be located in a directory whose six-digit SCRMET prefix matches that
of the data file.
Since each count represents about one second, there may be as many as nine
six-digit SCRMET prefixes with the same YYYYMMDD values. Also, since days
will not start or end exactly on 10,000 count SCRMET boundaries, directories
with the naming convention may span day boundaries. That is, the YYYYMMDD
value corresponding to the start of a 10,000 count SCRMET range may not be
the same as the YYYYMMDD that corresponds to the end of that range.
Explanation of granularity
--------------------------
The granularity of sub-directories under /DATA/ on this volume has been
copied from that used on the Science Operations Center (SOC) where the
data files were originally generated. On the SOC, the same granularity
was implemented across all eight New Horizons instruments' directory
structures. Because the mission instruments generate data files at
varying rates, from one or more data files per second to one or more days
per data file, a compromise granularity of 10,000 SCRMET counts was chosen,
and propagated to this volume.
Suggested FITS & PDS software
-----------------------------
For working with PDS-labeled data, software packages are available
at Planetary Data System (PDS) nodes (as of 2007). Several other options
for reading either FITS or PDS-labeled data are listed here. If not
included in the text below, references to the packages may be either found
at one or more PDS nodes or found via a search engine. Data users
planning to write custom software should refer to the PDS label
description in the subtopics that follow for a general introduction and
to the PDS Standards document available at PDS nodes.

N.B. The following description of PDS labels is only meant to be
sufficient to write a program to read the data, and is
therefore not a complete exposition. For full details
of the PDS standards, refer to the source from which this
dataset was obtained.
PDS label overview
-------------------
Each PDS label file is a multi-record flat ASCII file describing the
Data Units in a corresponding FITS data file that represent a single
observation or group of observations.
A FITS file is made up of one or more contiguous 2880-byte records.
Each Data Unit (DU) in a FITS data file comprises one or more records. The
data in each DU starts at the first byte of the DU and is arranged as
described
in the PDS label. If the data in a DU do not end at a 2880-byte boundary,
then that DU is padded out to the boundary.
Each record in a PDS label is 80 bytes long comprising 78 printable
7-bit ASCII characters and/or spaces and ending with a carriage return and a
line feed. Most records are of the form
KEYWORD = VALUE
where KEYWORD is the name of a quantity, and VALUE represents the value of
that quantity. Spaces before, after, and between the keyword, the equals
sign, and the value(s) are not significant.
String values may span multiple records, and are usually delimited
by (i.e. enclosed in) double quotes. Strings contain no double quotes.
Some string values, such as UTC times, are not enclosed in quotes.
Integer & floating point numeric values are displayed without quotes.
Multiple values for a single keyword are indicated by enclosing the
values in parentheses or curly braces and separating the values with commas.
Comments are initiated by a contiguous forward-slash & asterisk pair
(i.e. /*) on the left and continue to the end of a single record where they
are usually terminated by a matching asterisk & forward-slash pair (*/).
Blank lines may be inserted between other lines to enhance
readability.
1) PDS pointers
Pointers are special cases of keyword/value pairs in the PDS label,
and define where each DU starts in the FITS file; pointers look like this:
^HEADER = "XYZ.FIT" /* Primary Header DU (HDU) */
^IMAGE = ("XYZ.FIT",11) /* Primary DU */
^ERROR_HEADER = ("XYZ.FIT",22) /* Extension #1 HDU */
^ERROR_IMAGE = ("XYZ.FIT",31) /* Extension #1 DU */
^HOUSEKEEPING_HEADER = ("XYZ.FIT",43) /* Extension #2 HDU */
^HOUSEKEEPING_TABLE = ("XYZ.FIT",44) /* Extension #2 DU */
^THRUSTERS_HEADER = ("XYZ.FIT",45) /* Extension #3 HDU */
^THRUSTERS_TABLE = ("XYZ.FIT",51) /* Extension #3 DU */
N.B. The single quotes in the examples above are double quotes
in the actual labels.
Pointer keywords HEADER and IMAGE refer to the Primary Header
Data Unit (HDU) and Primary Data Unit, respectively. Pointer keywords that
end in _HEADER refer to Extension HDUs. Pointer keywords that end in _IMAGE
or _TABLE or _ARRAY refer to Extension DUs.
The text after the equals sign in each pointer is usually enclosed
by parentheses and comprises the filename of the file where the DU resides and
the DU's location in that file. The filename and the location are delimited
by a comma. The filename is a string enclosed in double quotes, and the DU
location is a decimal integer value indicating the cardinal location in the
file of the first 2880-byte record of the DU.
For example, the ^IMAGE DU above, with a location value of 11,
starts at an offset of 28800 bytes (= [11-1]*2880) from the first byte of the
file.
If only the filename is given, with neither the parentheses nor the
comma nor the location, then the DU starts at the beginning of the file i.e.
the location is implicitly set to one.
2) OBJECT stanzas
Each pointer in a PDS label will have a corresponding OBJECT
stanza. OBJECT stanzas comprise the lines between corresponding
'OBJECT=<object_name>' & 'END_OBJECT=<object_name>' keyword lines.
OBJECT stanzas referring to TABLEs will contain one or more
'OBJECT=COLUMN'/'END_OBJECT=COLUMN' stanzas.
See the comments (/* ... */) to the right of the keywords in the
example below to understand the OBJECTs and keywords that describe binary
tables.
************************************************************************
********** N.B. This example does not describe every keyword **********
********** that will be present in each table, but only **********
********** those necessary to read and understand the **********

************************************************************************
^S_TABLE = ("XYZ.FIT",51) /* EDU #3; Data table */
OBJECT = S_TABLE /* Start of object describing data of pointer ^S_TABLE */
INTERCHANGE_FORMAT = BINARY

DESCRIPTION = "..."
END_OBJECT = COLUMN
...
END_OBJECT = S_TABLE /* End of object S_TABLE */
************************************************************************
********** Example ends before the previous line *****************
************************************************************************
In the example above:
- the table S_TABLE starts at byte 144001 ((51-1)*2880 + 1)
of the file, and comprises 97 rows each of width 1080 bytes.
- the first column, named STATUSES, in each row starts at the
1st byte of that row and comprises three MSB-first 16-bit
integers using 6 bytes total on each row.
- the second column, named TEMPERATURE, in each row starts at
the seventh byte of that row and comprises one IEEE 32-bit
floating point value using four bytes total on each row.
- Subsequent rows are offset 1080 bytes from the previous row.
Generic PDS label details
-------------------------
The PDS label has meta-data which describe the circumstances
surrounding the data in the FITS file. These meta-data are in keyword and
value pairs (e.g. the pointers above) and each of these keywords is described
in the PDS Data Dictionary plus the New Horizons mission- specific local data
dictionary supplemental items, both of which are available in this archive.
All FITS Header Data Units (HDUs) and Data Units are described in the
PDS labels. In some cases, no Data Unit will be described in the PDS label
because there is nothing to describe i.e. it is not present in the FITS file.
PDS LABELS: Column Descriptions in binary tables
-------------------------------------------------
FITS extensions may contain data that are a subset of
instrument and/or spacecraft housekeeping telemetry packets
formatted as binary tables. Where possible, each column
included in such extensions has a DESCRIPTION field something
like this (double quotes have been replaced by single quotes):
DESCRIPTION = '
Full Mnemonic:
SWAP_RT.SEC64_ST
General Description:
A bit indicating the beginning of a 64-second cycle
Conversion: STATES
- [lo:hi]=state description:
[0:0]=CONT
[1:1]=START
Subsystem: SWAP
Packet ApID: 0X584
Byte Offset within ApID packet: 10
Bit Offset within Byte of ApID packet: 0
Bit Length within ApID packet: 1
Type of value: UNSIGNED
Units: N/A
'
The sub-fields used in these DESCRIPTION fields are as follows:
Full Mnemonic: The complete mnemonic used in the definition
of the packet. The COLUMN name will typically
be a subset of this mnemonic.
General Description: A description of the column
Extended Description: More information
- this field is not always present
Conversion: This item describes the conversion of the value
found in the column to a meaningful quantity.
It takes one of two forms: STATES and polynomial.
If the conversion form is STATES, then the bits of
the column are combined into an integer and compared
against the ranges list. In the example above, if the
value of the bit is zero, then the SWAP_RT.SEC64T
column represents a continuing state. If the value of
the bit is 1, then the SWAP_RT_SEC64T column indicates
that a new 64-second cycle has just begun.
If the conversion form is polynomial, then the bits of
the column are combined into an integer and used as
the independent value of the polynomial with the
coefficients given. For example, if the integer
value of a column is 100, and its conversion looks
like this:
Conversion: polynomial coefficients:
Order 0: 0.92516257733262
Order 1: 0.979219301744176
Then the derived value of this instrument is
0.925 + (0.97922 * 100) = 98.847
Subsystem: Which subsystem generated the packet
Packet ApID: The Application ID of the packet
Byte & Bit Offsets & Bit Length: the location of the column's
value in the packet, including
the 10-byte CCDS header.
Type of value: For integer values, whether the value
is signed or unsigned
Units: Nominal units of the derived column values
