the accurate knowledge of the beam profiles is a prerequisite for the calibration of extended sources of centre point source observations. it is not possible to cover all filter/aperture combinations to assess the beam profile shape. for this programme we perform the following filter aperture combination: 7.3 micron / 180 we will scan the aperture in y and z using a point source (star) in order to determine the aperture profile for the two combinations history 10/02/98\tcreation database for 180 scan (rjl) \t must be executed on rev 842 because of fixed position angle see also p1beam01 .ott 10072 sec .tdt 10792 sec

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.
