COSIMA DATA ARCHIVE 4.0
=======================

1. Introduction
---------------

This PDS dataset contains COSIMA data from the ground calibration
phase from 2002-05-29 up to the end of the escort phase 3 2015-10-20. 

COSIMA instrument has 72 different dust collecting substrates, in 
groups of 3 in 24 target holders. To understand the dust grain 
spectrum, one has to know the substrate background spectrum. For 
this reason, the operational history of each substrate is given. 
The history contains information about substrate storage and expose
periods, cleaning and heating actions, COSISCOPE camera images and
grains lists and any spectra taken. The history product contains 
history from the moment substrates were installed in the COSIMA 
flight instrument.

The user of the database is suggested to start from the 72 substrate
history products instead of the INDEX.TAB normally used in the PDS
datasets.

COSISCOPE camera can take 1024*1024 pixel images with 10 bit 
brightness information. Instead of sending full images, part of the 
image can be masked. In addition, COSISCOPE can detect prominent 
grains collected on the substrate during the expose. These grain 
lists contain size, position and brightness information. 

COSIMA uses Indium ion beam to extract secondary ions from the dust
grains. The time of flight mass spectrometer can detect ion events in
131072 time bins, each 1.953125 ns in length. The spectrum can be
divided to 3 subspectrums to reduce the telemetry. In addition, the 
mass scale can be established on board COSIMA and only the peaks of 
the first 300 organic and inorganic masses can be sent.

The COSIMA data in this archive has been provided by Finnish
Meteorological Institute. The instrument Primary Investigator is Dr
Martin Hilchenbach, Max Planck Institute for Solar System Research.

3. File formats
---------------

Data product files in this data archive are in ASCII format, except 
COSISCOPE images, which are binary.  Data products are TABLEs and 
FITS-images.

Documentation files are provided as PDF files.

COSIMA data products use attached labels. The labels point to 
external format containers (*.FMT files), saved in the LABEL 
subdirectory of this archive.

Data structure is described in the COSIMA SIS document, 
COSIMASIS.PDF, that can be found in the DOCUMENT subdirectory
