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: 11.5 micron / 52 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 11/02/98\tcreation database for 52 scan (rjl) \t must be executed on rev 842 because of fixed position angle 11/03/98 update for revolution 867 (tm) see also p1beam01

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.
