Abstract (from CDS):

We have built two samples of galaxies selected at 0.2µm (hereafter UV) and 60µm (hereafter FIR) covering a sky area of 35.36deg2. The UV selected sample contains 25 galaxies brighter than AB0.2=17. All of them, but one elliptical, are detected at 60µm with a flux density larger or equal to 0.2Jy. The UV counts are significantly lower than the Euclidean extrapolation towards brighter fluxes of previous determinations. The FIR selected sample contains 42 galaxies brighter than f60=0.6Jy. Except four galaxies, all of them have a UV counterpart at the limiting magnitude AB0.2=20.3mag. The mean extinction derived from the analysis of the FIR to UV flux ratio is ∼1mag for the UV selected sample and ∼2mag for the FIR selected one. For each sample we compare several indicators of the recent star formation rate (SFR) based on the FIR and/or the UV emissions. We find linear relationships with slopes close to unity between the different SFR indicator, which means that, over the whole converting offset. Various absolute calibrations for both samples are discussed in this paper. A positive correlation between extinction and SFR is found when both samples are considered together although with a considerable scatter. A similar result is obtained when using the SFR normalized to the optical surface of the galaxies.
