| Description | it has been shown that pht-s chopped measurements (especially at low fluxes) can be reasonably well modelled by fouks function, including signal jumps between chopper plateaux. since the correction may change the photometry it becomes necessary to check the algorithm by application to known calibration stars. on the other hand, a spectral response function can be derived from these measurements, then such function will be consistently applied to drift corrected measurements. we propose to observe around 5 calibration stars (from 1.7 to 6.6 k magnitudes) which cover the range of all chopped observations perfomed up to now. |

| Mission Description | The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths. |
