Abstract:
This work presents the main ultraviolet (UV) and far-infrared (FIR)
properties of two samples of nearby galaxies selected from the GALEX
(λ=2315Å, hereafter NUV) and IRAS (λ=60µm)
surveys, respectively. They are built in order to obtain detection at
both wavelengths for most of the galaxies. Star formation rate (SFR)
estimators based on the UV and FIR emissions are compared. Systematic
differences are found between the SFR estimators for individual
galaxies based on the NUV fluxes corrected for dust attenuation and on
the total IR luminosity.

--------------------------------------------------------------------------------
Note (1): From the 2MASS Extended Source Catalog. For galaxies with no
detection at 2MASS we adopt the limiting value of Hmag=13.9mag (3mJy)
as given by Jarrett et al. (2000AJ....119.2498J 2000AJ....119.2498J).
Note (2): Derived as indicated in Buat et al. (2005ApJ...619L..51B 2005ApJ...619L..51B). For
some galaxies Eqs. 1 and 2 gave negative values of the NUV and FUV
attenuations which is senseless. In fact, this is an artifact of the
polynomial fitting used to derive a functional form for the
attenuation in Buat et al. (2005ApJ...619L..51B 2005ApJ...619L..51B). Throughout this
paper they will be considered as zero.

accounts for the IR cirrus emission and SFRNUV0 is obtained
following Eq. 3 but using the observed NUV luminosity LNUV,obs
instead of LNUV,corr.
