Performance and Calibration

The characterisation of the instrument behaviour in-flight, its calibration, the corresponding data processing methods and caveats applicable to archive data products are described in the different volumes of the ISO Handbook:

• Volume I: ISO - Mission & Satellite Overview (Version 2.0)
• Volume II: CAM - The ISO Camera (Version 2.0)
• Volume III: LWS - The Long Wavelength Spectrometer (Version 2.1)
• Volume IV: PHT - The Imaging Photo-Polarimeter (Version 2.0.1)
• Volume V: SWS - The Short Wavelength Spectrometer (Version 2.0.1)

The ISO Handbook volumes give a summary on how to use ISO data in general. More detailed information can be found in the technical reports and calibration publications under the CAM Instrument Page, LWS Instrument Page, PHT Instrument Page and SWS Instrument Page.

Cross-Calibration

The ISO cross-calibration between the different subinstruments and with external facilities is analysed in a series of status reports issued every 6 months during Post-Operations.

• ISO (Cross-)Calibration Final Report (17/Oct/2003)
• 4th Post-Operations Cross-Calibration Status Report (08/Jan/2001)
• 3rd Post-Operations Cross-Calibration Status Report (03/Jul/2000)
• 2nd Post-Operations Cross-Calibration Status Report (21/Feb/2000)
• 1st Post-Operations Cross-Calibration Status Report (28/Jul/1999)
