Issue Date: | 2020 | Journal: | ASTRONOMY & ASTROPHYSICS | Number: | 637 | First Page: | A54 | Abstract: | Context. This is the second u-band extension of the WIde-field Nearby Galaxy-cluster Survey (WINGS) whereby 39 clusters were imaged with the ESO-VLT survey telescope. This follows the first part of the survey which was performed with several telescopes of the northern hemisphere in the U Cousin-Bessel filter band covering 17 clusters. <BR /> Aims: The u-band data, in combination with those already collected by the WINGS survey, permit a detailed multi-wavelength investigation of the properties of the member galaxies from the cluster center out to the periphery. <BR /> Methods: We used SExtractor to derive the main properties of the galaxies in the observed fields and measure the u - V colors on circular apertures of increasing radius. The photometric accuracy of the magnitudes was calibrated with the standard stars and was tested by means of comparisons with the u-band data of the Sloan Digital Sky Survey (SDSS). <BR /> Results: We present the catalogs of the photometric analysis performed by SExtractor. We also provide a brief analysis of the u - V versus V color-magnitude diagram of our clusters, the plots of the color as a function of the cluster-centric distance (for cluster members only), the mass-color relation and the correlation of the current star formation rate (SFR) with the absolute V and u magnitudes for the galaxies in the observed fields. <P />Full Table A.1 is only available at the CDS via anonymous ftp to <A href="http://cdsarc.u-strasbg.fr/">http://cdsarc.u-strasbg.fr</A> (ftp://130.79.128.5) or via <A href="http://cdsarc.u-strasbg.fr/viz-bin/cat/J/A+A/637/A54">http://cdsarc.u-strasbg.fr/viz-bin/cat/J/A+A/637/A54</A> <P />Based on observations collected at the European Southern Observatory under ESO GTO programs IDs (089.B-0683-098.B-0657). | URI: | http://hdl.handle.net/20.500.12386/32603 | URL: | https://www.aanda.org/articles/aa/full_html/2020/05/aa37823-20/aa37823-20.html https://api.elsevier.com/content/abstract/scopus_id/85088112105 |
