currently we recommend four different observing strategies to the observer as outlined in .detection limits and observing strategy for very faint point sources. (sai/96-188/doc, laureijs et al). from the available observations we can deduce the detection limits in the 90 micron band, and concerning signal derivation we see a preference for the telescope nodding technique. from our recent c200 measurements (see report on isophot c160 observations of hr 6132 by abraham et al. from 14/10/96) we have found, that in case of significant cirrus contamination two reference positions may not be sufficient in order to derive the true background level and the amplitude of the background fluctuations. the c100 and c200 detectors behave different w.r.t. noise and signal transients which are considered to be essential criteria for selection of the right mapping mode. date:\t20/11/96 u. klaas, r.j. laureijs .ott 10362 .tdt 11702
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.
