The European large area ISO survey: ELAIS
Résumé
The European Large Area ISO Survey (ELAIS) has surveyed ~ 12 square degrees of the sky at 15 and 90 μ m and subsets of this area at 6.75 and 175 μ m using the Infrared Space Observatory (ISO). This project was the largest single open time programme executed by ISO, taking 375 hours of data. A preliminary catalogue of more than 1000 galaxies has been produced. In this paper we describe the goals of the project, describe the follow-up programmes that are in progress, and present some first scientific results including a provisional number count analysis at 15 and 90 μ m.
