===================================================================== ==> in this proposal, more time is being requested for jbalutea.ism_v ===================================================================== two bright astronomical sources were proposed to be observed over the spectral range covered by the lws, from 47 to 196 microns, in the high resolution fabry-perot mode. the main goal of this lws guaranteed time proposal (jbalutea.ism_v) was to detect new spectral features or lines with unexpected strength. in order to get the full high resolution capability of the isolws together with a very high signal to noise ratio (about 100) the sources were selected to be extremely bright and adequate for probing in the best possible way the different phases associated with the interstellar medium. the sources selected for the iso autumn launch were in 1st priority, sgr b2 (main) and in 2nd priority, m17. because of the change of sensitivity of the lws due to the cosmic particles hits onto the detectors, and because of the increase of the iso lifetime, the initial proposal had been modified. sgr b2 has been kept at the 1st priority but m17 was replaced by orion bn/kl (our 1st priority source in the spring launch list). however the time allocated to the cp proposal is now insufficient to carry out the whole programme, due to the increase of time required by the changes in the aot lws03 logics. presently, in the cp programme the available time allows a full spectral survey from 47 to 196 um of sgr b2 (main) and a spectral coverage of orion bn/kl limited to only 47 - 70 um. the present proposal intends to permit the extension of the spectral coverage of orion bn/kl from 70 to 196 um.

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.
