The European Large Area ISO Survey - ISOPHOT results using the MPIA-pipeline
The European Large Area ISO Survey (ELAIS) will provide Infrared observations
of 4 regions in the sky with ISO. Around 2000 Infrared sources have been
detected at 7 and 15 microns (with ISOCAM), 90 and 175 microns (with ISOPHOT))
over 13 square degrees of the sky. We present the source extraction pipeline of
the 90 microns ISOPHOT observations, describe and discuss the results obtained
and derive the limits of the ELAIS observational strategy.Comment: 4 pages, 5 figures, to appear in the ISO conference "The Universe as
seen by ISO", 1998, UNESCO, Pari
The evolution of type 1 AGN at 15 μm from ELAIS
We present the first preliminary estimate of the evolution of type 1 AGNs at 15μm. A new sample of sources selected from the ELAIS-S1 survey has been used together with the RMS sample. The ELAIS-S1 survey covers an effective area of 2.2 deg2 (total: 4 deg2) down to 1.2 mJy at 15 μm. Spectroscopic identifications have been carried out in the range 17.2 < R < 20.0 at the 3.6m/ESO, NTT/ESO and 2dF/AAT. The luminosity function is steeper at bright luminosities in comparison to the previous estimates of Rush, Malkan & Spinoglio (1993). The evolution is compatible with a Pure Luminosity Evolution model with L(z) ~ L(0)(1+z)3.4
ELAIS: final band-merged catalogue
The catalog represents the final band-merged European Large-Area ISO Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175{mu}m, and the associated data at U, g', r', i', Z, J, H, K and 20cm. Details about the origin of the survey, the observations, data reduction and optical identification are described in the paper. In addition to fluxes in the radio, infrared and optical passbands, spectroscopic redshifts are tabulated, where available. For the N1 and N2 areas, the Isaac Newton Telescope ugriz Wide Field Survey permits photometric redshifts to be estimated for galaxies and quasars
