ROSINA ARCHIVE FOR THE EARLY MISSION PHASES
1. Introduction
This archive contains engineering data of the ROSINA instrument on ROSETTA. It
also contains documentation which describes the ROSINA mass spectra and the
related instruments and detectors.
The ROSINA mass spectra archived in this data set are the exact products as
described in the ROSINA Experiment to Archive Interface Document(EAICD),
version 1.2. Supporting documentation and label files
conform to the Planetary Data System (PDS) Standards, Version 3.6, Jet
Propulsion Laboratory (JPL) document JPL D-7669, Part 2.
Additional information about the ROSINA experiment can be found in documents
on ESA's file servers and from the PDS Small bodies Node.
2. Volume format
N/A
3. File formats
The ROSINA experiment produces two kind of data, mass spectra and pressure
records. All data files are in pure ASCII and use up to two TABLE objects with
attached labels. The RECORD_TYPE is fixed length with 80 bytes records.
Structure pointers, which describe the table COLUMNs, are defined in
the labels in order to keep it easy readable.
All document files (exept PDF format) contain 80-byte fixed-length records,
with a carriage return character (ASCII 13) in the 79th byte and a line feed
character (ASCII 10) in the 80th byte. This allows the files to be read by the
MacOS, DOS, Unix, and VMS operating systems. All tabular files are described
by attached PDS labels.
Tabular files are formatted so that they may be read directly into many
database management systems on various computers. All fields are separated by
commas, and character fields are enclosed in double quotation marks (").
Character fields are left justified, and numeric fields are right justified.
The "start byte" and "bytes" values listed in the labels do not include the
commas between fields or the quotation marks surrounding character fields. The
records are of fixed length, and the last two bytes of each record contain the
ASCII carriage return and line feed characters. This allows a table to be
treated as a fixed length record file on computers that support this file type
and as a normal text file on other computers.
PDS labels are object-oriented. The object to which the label refers (e.g.,
IMAGE, TABLE, etc.) is denoted by a statement of the form:
^object = location
in which the carat character (^, also called a pointer in this context)
indicates that the object starts at the given location. In an attached label,
the location is an integer representing the starting record number of the
object (the first record in the file is record 1). In a detached label, the
location denotes the name of the file containing the object, along with the
starting record or byte number. For example:
^TABLE = "INDEX.TAB"
indicates that the TABLE object points to the file INDEX.TAB .
Pointers to data objects are always required to be located in the same
directory as the label file, so the file INDEX.TAB in this example is located
in the same directory as the detached label file.
Other types of pointer statements can also be found in this dataset.To resolve
the pointer statement, first look in the same directory as the file containing
the pointer statement. If the pointer is still unresolved, look in the
following top level directory:
^ STRUCTURE - LABEL directory
^ CATALOG - CATALOG directory
^DATA_SET_MAP_PROJECTION - CATALOG directory
^DESCRIPTION - DOCUMENT directory.
Below is a list of the possible formats for the ^object keyword.
^object = n
^object = n (used for our TABLES)
^object = "filename.ext" (used for COLUMN definitions)
^object = ("filename.ext",n)
^object = ("filename.ext",n)
where
n is the starting record or byte number of the object,
counting from the beginning of the file (record 1,
byte 1)
indicates that the number given is in units of bytes
filename is the upper-case file name
ext is the upper-case file extension
4. Dataset contents
The files in this dataset are organized in one top level directory with
several subdirectories. The following table shows the structure and content of
these directories. In the table, directory names are enclosed in square
brackets ([]), upper-case letters indicate an actual directory or file name,
and lower-case letters indicate the general form of a set of directory or file
names.
