| Description | we want to use the 23 arsec aperture for high resolution sampling with 8 arsec step size. in order to have a good determination of the baseline of the scan two full aperture sizes outside the disk will be measured. an important check of any spatial extended structure in this observing mode is the repetition of the same measurement on a true point source with the same s/c orientation (preferentially use s/c y-axis orientation). vegas brightness at 60 micron is around 5 jy. a star of similar brightness is gamma dra (hr 6705). the scan over hr 6705 can also be used in order to better determine the point spread function at 60 micron. history:\t\t07/02/97\tfirst pga version with 13 steps; uk, rjl 11/02/97 raster step size changed to 6 (jh.lo-mt, uk) .ott 8650 .tdt 9010 |

| 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. |
