ISO observations spatially resolved a variety of objects ranging from planets, circumstellar envelopes, and galaxies, to structures with larger angular sizes like comet trails, interstellar clouds, and star forming regions. It is also possible to investigate the properties of the zodiacal, galactic, and extra- galactic backgrounds since ISO measured the absolute brightness level of the infrared sky.
The analysis of extended sources presents new challenges compared to the analysis of point sources. In most cases, expertise is required in surface brightness calibration, map construction, and source flux extraction to arrive at reliable results and interpretation. Comparison of results with data from other experiments is often highly desirable.
This workshop aims at bringing together scientists, who are working on programmes in which extended emission is important, to exchange results and experiences. Spectroscopy on extended sources is included. We invite participants to give presentations concentrating on the scientific case of their project.
The registration form can be found here and the deadline for abstracts is: August 1, 1999
