Together with the data reported earlier the total I-band coverage of EIS is 17 square degrees, which has yielded a sample of 302 cluster candidates with estimated redshift in the range 0.2≤z≤1.3 and a median redshift of z=0.5. This is the largest optically-selected sample currently available in the Southern Hemisphere. It is also well distributed in the sky thus providing targets for a variety of VLT programs nearly year round. File Summary:

Note (1): the Λcl richness parameter was introduced by Postman et al. (1996AJ....111..615P). NR is the Abell richness class (number of member galaxies within a 2-mag interval starting at the 3rd brightest member) See details in paper II, Olsen et al., 1999A&A...345..681O
