The ESO-Sculptor survey with ISO

International audienceThe ESO-Sculptor deep redshift survey (de Lapparent et al. 1997), nearly complete down to R = 20.5, contains ~= 700 galaxies in the configuration of a thin strip ~= 0.2 x 1 square degrees, reaching out to a redshift of ~= 0.5. In order to build an IR luminosity function, to detect possible traces of ultraluminous galaxies as well as to analyze the far-IR properties of normal galaxies, the European Large Area ISO Survey (ELAIS) Survey observed a small (24^' x 24^') region of the ESO-Sculptor survey with ISOPHOT. About 14 infrared sources have been detected with a flux \gt 30 mJy . With an error box of one pixel, the cross-correlation requires an improved data processing of the source extraction pipeline and complementary data
