62 CHAPTER 9. THE DATA PRODUCTS AND CIA DATA STRUCTURES
explanation of these data types and the files where actual data may be found follows. This may
notbeanexhaustivereview 2 of the data products but should suffice at this stage.
9.3.1 Raw data products
The ISOCAM raw data products consist of CAM Compact Status Data and CAM Edited Raw
Data.
Compact Status Data (CSTA) Data on the status of ISOCAM during the observation. It
is delivered in the CSTA file. ISO CD-ROM users can find this file in the directory
/products/pmmmmmmm/nnnxxxyy. Though used by some routines 3 these data are not
essential.
CAM Edited Raw Data (CIER) ERD refers to raw CAM data. These are all the data from
and associated with an observation, including internal calibration and housekeeping data.
These data are delivered to you in the CIER file 4 . ISO CD-ROM users can find this file
in the directory /products/pmmmmmmm/nnnxxxyy.
9.3.2 Standard Processed Data (SPD)
SPD are data which have had some processing. Housekeeping data has been removed and
IMAGEs are computed from the RESET and End-Of-Integration (EOI) FRAMEs that are
present in CIER. These data are delivered in the CISP file 5 . ISO CD-ROM users can find this
file in the directory /products/pmmmmmmm/nnnxxxyy.
9.3.3 Automatic Analysis Results (AAR)
The AA processing produces several data products. CCIM, CMAP and CMOS files primarily
contain processed images. The remaining files contain by-products of the AA, for example CGLL
contains a list of glitches detected by AA processing. ISO CD-ROM users can find this file in
the directory /products/pmmmmmmm/nnnxxxyy.
• Primary AAR level data products containing ISOCAM images:
CCIM Contains AA computed EXPOSUREs in detector coordinates.
CMAP Contains AA computed EXPOSUREs in astronomical coordinates.
CMOS CAM Mosaic. Contains MOSAICS constructed by AA from EXPOSUREs, contained
in the CMAP data product, of the same CONFIGURATION.
• By-products of AA processing:
CUFF CAM User-friendly File. Contains a log of messages from AA processing.
CGLL CAM Glitch List. Contains a list of AA detected glitches.
CJAM CAM Jitter, Memory and Stabilisation information.
CPSL Contains a catalogue of AA detected point sources.
CSSP Contains the measured spectrum for each point source detection. Used in multifilter
observations only.
2 Refer to the ISOCAM Handbook and the ISO Data Product Document for a comprehensive account.
3 Currently x slicer (see Section 12.3) uses the CSTA data product though it will work without it.
4 CAM parallel ERD data are delivered in the CPER file and CAM Diagnostic ERD data in the CDER file.
5 CAM parallel SPD data are delivered in CPSP.
