Issue Date: | 2016 | Journal: | VizieR Online Data Catalog | First Page: | J/AJ/151/78 | Abstract: | WIde-field Nearby Galaxy-cluster Survey (WINGS) is a large survey targeting 76 clusters of galaxies selected on the basis of their X-ray luminosity (Ebeling et al. 1996, Cat. J/MNRAS/281/799; Ebeling et al. 1998, Cat. J/MNRAS/301/881; Ebeling et al. 2000, Cat. J/MNRAS/318/333), covering a wide range in cluster masses (σ=500-1200+km/s, logL<SUB>X</SUB>=43.3-45erg/s, Fasano et al. 2006A&A...445..805F). The original WINGS data set consisted of B and V deep photometry of a 34'*34' field of view with the WFC@INT and the WFC@2.2mMPG/ESO (Varela et al. 2009, Cat. J/A+A/497/667), spectroscopic follow-ups with 2dF@AAT and WYFFOS@WHT (Cava et al. 2009, Cat. J/A+A/495/707), plus J and K imaging with WFC@UKIRT (Valentinuzzi et al. 2009, Cat. J/A+A/501/851) and some U-band imaging (Omizzolo et al. 2014, Cat. J/A+A/561/A111). This database is presented in Moretti et al. 2014A&A...564A.138M and has been employed for a number of studies (see https://sites.google.com/site/wingsomegawings/). <P />OmegaCAM-VST observations of WINGS galaxy clusters (OMEGAWINGS) is a recent extention of this project, that quadruples the area covered (1deg<SUP>2</SUP>) and allows to reach up to ~2.5 cluster virial radii. OMEGAWINGS is based on two OmegaCAM@VST GTO programs for 46 WINGS clusters: a B and V campaign completed in P93, and an ongoing u-band programme. The B and V data, the data reduction and the photometric catalogs are presented in Gullieuszik et al. 2015 (Cat. J/A+A/581/A41). Spectra are obtained with AAOmega@AAT on the OmegaCAM field. So far, we have secured high quality spectra for ~30 OMEGAWINGS clusters, reaching very high spectroscopic completeness levels for galaxies brighter than V=20 from the cluster cores to their periphery (A. Moretti et al. 2016, in preparation). Galaxies are considered cluster members if they are within 3σ from the cluster redshift. The mean redshift uncertainty, computed from the differences between WINGS and OMEGAWINGS redshift values of repeated objects, is ∆z=0.0002. <P />For this paper we consider the 41 OMEGAWINGS clusters with an OmegaCAM B and/or V-band seeing {<=}1.2arcsec, listed in Table1. To complete the search within the WINGS sample, we used the old WINGS images for other 31 clusters not observed with OmegaCAM (Table1). <P />The reference comparison field sample for WINGS and OMEGAWINGS is the Padova Millennium Galaxy and Group Catalog (PM2GC; Calvi et al. 2011, Cat. J/MNRAS/416/727), built from the Millennium Galaxy Catalogue (MGC; Liske et al. 2003, Cat. VII/240), a deep 38deg<SUP>2</SUP> INT B-imaging survey with a highly complete spectroscopic follow-up (96% at B=20, Driver et al. 2005, Cat. VII/240). | URI: | http://hdl.handle.net/20.500.12386/24400 | URL: | http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=J/AJ/151/78 | Bibcode ADS: | 2016yCat..51510078P | Fulltext: | open |
