1.2 Structure

In this document we present information on:

• the ISOCAM instrument and its observing modes,
• the processing steps carried out on the raw data,
• the calibration of the instrument,
• the uncertainties in the data,
• the final ISOCAM archive products.

An overview of the ISOCAM instrument is given in Chapter 2. In Chapter 3 the modes in which ISOCAM could observe are presented. The in-orbit performance is described in Chapter 4 together with estimates of the uncertainties expected in ISOCAM data. A summary of the various ISOCAM data products available in the ISO Data Archive is given in Chapter 5. The results of the individual calibration measurements are archived in calibration libraries, which are described in Chapter 6. An overview of the Off-Line Processing (OLP) pipeline for ISOCAM data is given in Chapter 7. The main caveats applicable to the automatic data processing system (OLP) are described in Chapter 8. Finally, a short description on how to get started with ISOCAM data is presented in Chapter 9.

Several appendices are attached to give more detailed information on individual subjects.
