Content of the catalogue

This catalogue contains 168 ISOPHOT measurements of 11 compact solar-system objects (planets or asteroids). They were observed in mini-map mode with the C100/C200 detectors after revolution 95.

Availability

The catalogue was submitted to ISO Data Archive in Dec 2003, and became available for the public via the ISO Data Archive web in Feb 2004.

Special processing features

  • correction for short-term signal transients;
  • correction for long-term baseline variations;
  • check if the object is point-like or extended;
  • an additive correction for the photometric zero point offset at low flux level;
  • a multiplicative correction for systematic photometric deviations at high flux level.

The corrections were developed and tested on the stellar sample itself, predicting model fluxes from their K-magnitudes and assuming that the majority of them do not exhibit any infrared excess.

Typical photometric accuracies

The average error bars are ~5-8% for bright sources and 15(C100), 30(C200) mJy for faint sources. The latter value is about a factor of 3 better than the IRAS FSC. For small extended sources special treatment.
