INTEGRAL data

An INTEGRAL revolution of three days (about 72 hours) results in a telemetry volume of approximately 2Gb. This telemetry stream is processed and analyzed at the ISDC and will result in about 15Gb of uncompressed data products per revolution. These data are stored in FITS files and consist of:

• raw data (4.5Gb), which are reformatted data with the same information content as the telemetry sent by the spacecraft,
• prepared data (7.2Gb) including additional timing information,
• corrected data (2.7Gb) including gain corrected event energy.

All these data are distributed in a compressed format ( 9 Gb per revolution) to the observers. Proposers should be therefore aware that they need more than 10Gb of disk-space to store INTEGRAL observations that last about one revolution.
