ISO Callibration

The ISO Ground Based Preparatory Programme


GBPP Stars

Below you can find the list of stars originally included in the ISO Ground Based Preparatory Programme. Note that flux densities quoted are predictions. Look at the IRAS Point Source Catalogue for accurate values.

GBPP Photometry

The tables below contain both Northern data from La Palma and Teide observatories (P. Hammersley) and Southern data from ESO-La Silla (N. van der Bliek, J. Manfroid and P. Bouchet).

Caution: Some of these stars have been found to be slightly variable or multiple by Hipparchos; see list of possible problem stars for further details.

Near IR data sets

There are 4 files containing the near IR data compiled as part of the ISO Ground Based Preparatory Programme. For each filter you will find (1) the magnitude of the star, (2) the stated error in the magnitude, and (3) the number of measurements.

The colour error files contain the difference between the measured colours and the predicted colours for the stars in the sample, according to their assumed effective temperature. Everything is based on empirical fits. The size of the error across the various colours give a good indication as to how 'good' the stars are for calibration purposes.
