We have built two samples of galaxies selected at 0.2micron (hereafter UV)and 60micron (hereafter FIR) covering a sky area of 35.36 deg^2. The UVselected sample contains 25 galaxies brighter than AB_0.2=17mag. All of them,but one elliptical, are detected at 60micron with a flux density larger orequal to 0.2Jy. The UV counts are significantly lower than the euclideanextrapolation towards brighter fluxes of previous determinations. The FIRselected sample contains 42 galaxies brighter than f_60=0.6Jy. Excepting fourgalaxies, all of them have a UV counterpart at the limiting magnitudeAB_0.2=20.3mag. The mean extinction derived from the analysis of the FIR to UVflux ratio is ~1mag for the UV selected sample and ~2mag for the FIR selectedone. For each sample we compare several indicators of the recent star formationrate (SFR) based on the FIR and/or the UV emissions and we find linearrelationships with slopes close to unity, meaning that no trend with the SFRexists when converting between each other. Various absolute calibrations forboth samples are discussed in this paper. A positive correlation betweenextinction and SFR is found when both samples are considered together althoughwith a considerable scatter. A similar result is obtained when using the SFRnormalized to the optical surface of the galaxies.Comment: 34 pages, 17 figures. Accepted for publication in A&
