| 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 ngc628: background and star staring plus chopped measurements. several filters are taken to have several contrast levels between background and source. the measurement includes staring and chopped observations .history 23/06/97 ja first version. standard star is hr5340 26/08/97 ja standard star is hr6705 09/09/97 ja new version for ngc6543 (c200) 18/11/97 ja new version for ic 5201 (c100 & c200) 03/12/97 ja new version for ngc628 (c200: 120,135 and 200um) .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. |
