Description the following program is carried out in order to consolidate the pht calibration of chopped measurements and derive signal losses due to the high chopper frequency compared to signal stabilization time. we intend to use well known calibration stars with a consolidated spectral energy distribution. the star is sufficiently bright to be used as a standard at wavelengths longward of 60 micron. since the star is very bright at the shorter wavelengths background observations are taken only for filters longward of 60 micron. several filters are taken to have several contrast levels between background and source. a second set of measurements is taken using shorter reset interval, in order to increase the chopper frequency. to do this we have to increase the fluxes to the double of its value. .history 23/06/97 ja first version. standard star is hr5340 26/08/97 ja standard star is hr6705 26/02/98 ja p3 on hr1457

Mission Description The Infrared Space Observatory (ISO) was the world's 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.
