A 12 µm ISOCAM survey of the ESO-Sculptor field. Data reduction and analysis.


Abstract (from CDS):

We present a detailed reduction of a mid-infrared 12µm (LW10 filter) ISOCAM open time observation performed on the ESO-Sculptor Survey field (Arnouts et al., 1997A&AS..124..163A). A complete catalogue of 142 sources (120 galaxies and 22 stars), detected with high significance (equivalent to 5σ), is presented above an integrated flux density of 0.24mJy. Star/galaxy separation is performed by a detailed study of colour-colour diagrams. The catalogue is complete to 1mJy and, below this flux density, the incompleteness is corrected using two independent methods. The first method uses stars and the second uses optical counterparts of the ISOCAM galaxies; these methods yield consistent results. We also apply an empirical flux density calibration using stars in the field. For each star, the 12µm flux density is derived by fitting optical colours from a multi-band χ2 to stellar templates (BaSel-2.0) and using empirical optical-IR colour-colour relations. This article is a companion analysis to our 2007 paper (Rocca-Volmerange et al., 2007A&A...475..801R) where the 12µm faint galaxy counts are presented and analysed per galaxy type with the evolutionary code PEGASE.3.
