the accurate knowledge of the straylight is a prerequisite for an accurate photometric calibration of the isophot-p subexperiment. the aim of the proposed observation with pht-p2 is the determination of the straylight contribution from sources outside the field-of-view. this measurement is the last in a series of three similar exploratory measurements carried out on pht-s and c200, which will be the base to review eventual more sensitive measurements on the sun and earth. .history 20/01/97\tuk, rl, first version based on proposal by d. lemke et al. \t\t\t(email 18/12/96) .ott 15371 .tdt 16756

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.
