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 1983ApJS...52..183B, Butcher & Oemler, 1984ApJ...285..426B 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.
