we propose to observe the cooling lines cii and oi (63 microm) in 2 clouds which will be observed with phot already in selected positions during the isophot guaranteed time programme. our aim is to compare the cii and oi line emission to the fir dust continuum emission in order to determine the efficiency of the photoelectric heating mechanism by observing cuts through the cloud edges. also the role of pahs in the heating balance will be studied.

Mission Description
The Infrared Space Observatory (ISO) was the world's 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.
