Aims. We present the B-, V- and K-band surface photometry catalogs obtainedrunning the automatic software GASPHOT on galaxies from the WINGS clustersurvey having isophotal area larger than 200 pixels. The catalogs can bedownloaded at the Centre de Donnees Astronomiques de Strasbourg (CDS). Methods.We outline the GASPHOT performances and compare our surface photometry withthat obtained by SExtractor, GALFIT and GIM2D. This analysis is aimed atproviding statistical information about the accuracy generally achieved by thesoftwares for automatic surface photometry of galaxies. Results. For eachgalaxy and for each photometric band the GASPHOT catalogs provide theparameters of the Sersic law best-fitting the luminosity profiles. They are:the sky coordinates of the galaxy center (R:A:; DEC:), the total magnitude (m),the semi-major axis of the effective isophote (Re), the Sersic index (n), theaxis ratio (b=a) and a flag parameter (QFLAG) giving a global indication of thefit quality. The WINGS-GASPHOT database includes 41,463 galaxies in the B-band,42,275 in the V-band, and 71,687 in the K-band. We find that the brightearly-type galaxies have larger Sersic indices and effective radii, as well asredder colors in their center. In general the effective radii increasesystematically from the K- to the V- and B-band. Conclusions. The GASPHOTphotometry turns out to be in fairly good agreement with the surface photometryobtained by GALFIT and GIM2D, as well as with the aperture photometry providedby SExtractor. The main advantages of GASPHOT with respect to other tools are:(i) the automatic finding of the local PSF; (ii) the short CPU time ofexecution; (iii) the remarkable stability against the choice of the initialguess parameters. All these characteristics make GASPHOT an ideal tool forblind surface photometry of large galaxy samples in wide-field CCD mosaics.
