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. - observation of ngc7640: chopped measurements and nodding as reference. several filters are taken to have several contrast levels between background and source. the measurement includes staring and chopped observations .history 10/12/97 ja new version for ngc7640 (c100: 60 and 105um) .ott 2639 .tdt 2179

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.
