The r'-band luminosity function of Abell 1367: A comparison with Coma.

Abstract (from CDS):

We made a large (approximately 1°x1°) r'-band imaging survey of the central regions of the two nearby clusters of galaxies, Abell 1367 and Coma. The data, presented as a catalog, are used to construct the r'-band luminosity function (LF) of galaxies in these two clusters, by subtracting the Yasuda et al. (2001AJ....122.1104Y) galaxy counts from our cluster counts. Our Coma luminosity function is consistent with previous determinations, i.e. providing a faint end slope α= -1.47–0.09+0.08, significantly steeper than the one we find for Abell 1367 (α=-1.07–0.16+0.20). The counts in Abell 1367 show a relative minimum at r'≃19, followed by a steep increase faintward. The difference between the two clusters appears significant, given the consistency of the experimental conditions in the two clusters. Whereas for Coma we find a significant increase of the slope of the LF outwards, no such effect is found for Abell 1367.
