ESO Imaging Survey. VII. Distant cluster candidates over 12 square degrees. Scodeggio M., Olsen L.F., Da Costa L., Slijkhuis R., Benoist C., Deul E., Erben T., Hook R., Nonino M., Wicenec A., Zaggia S. <Astron. Astrophys. Suppl. Ser. 137, 83 (1999)> =1999A&AS..137...83S

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
