observing strategy and detection limit with c_160 previous test observations with the c_160 filter (sao214134 and sao248381, both 23 mjy, and theta umi, 46 mjy) have failed to detect the target stars, therefore new observations of a somewhat brighter target are necessary. we propose to observe hr6132 from the gbpp list with c_160, using all four different observing modes listed in the report .detection limits and observing strategy for very faint point sources. (sai/96-188/doc, laureijs et al.). the star has a predicted brightness of 75 mjy at 175 um, and is located at a very low background environment. the results will help to answer the following questions: - which observing mode provides the best detection limit? - is the signal of the chopped measurement smaller than the signal derived from staring measurement? is this effect observable in case of p32 oversampled maps as well? - does the 2x4 raster provide higher signal than the staring measurement? uk, rjl 12/09/96

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.
