J/A+AS/95/87        Photometry and Spectroscopy in A2218    (Le Borgne+, 1992)

Photometric and spectroscopic survey of the cluster of galaxies Abell 2218. Le Borgne J.F., Pello R., Sanahuja B. <Astron. Astrophys. Suppl. Ser. 95, 87 (1992)> =1992A&AS...95...87L
ADC_Keywords: Clusters, galaxy ; Galaxies, photometry ; Radial velocities Keywords: clusters of galaxies: Abell 2218 Abstract: We present new photometric and spectroscopic observations of objects in the field of the cluster of galaxies Abell 2218. The photometric survey, centered on the cluster core, extends to a field of about 4'x4'. It was performed in 5 bands (B, g, r, i and z filters). This sample, which includes 729 objects, is about three times larger than the survey made by Butcher and collaborator (Butcher et al., 1983ApJS...52..183B, Butcher & Oemler, 1984ApJ...285..426B) in the same central region of the field. Only 228 objects appear in both catalogues since our survey covers a smaller region. File Summary:
