Abstract
Identifications of a large number of galaxy clusters in the Lick map, using an algorithm based on an overdensity criterion, are presented. The resulting catalogues contain ∼ 6000 clusters (with |b| ≥ 40°) out of which 753 are Abell clusters. Ellipticities and major axis orientations for a suitable subset of this sample, including 397 Abell clusters, are determined. It is found that the distribution of projected axial ratios is approximately Gaussian. Methods are investigated to invert the distribution of apparent axial ratios in order to obtain the distribution of intrinsic axial ratios. The apparent shapes of clusters in the sample are found inconsistent with those expected from a population of oblate spheroids seen in projection
