... We carried out follow-up spectroscopy of 178 Case galaxies in the zone - 16 h , and - +38 ,classified in the Case catalog with some code, indicating the presence of the line [O III ] 5007, and not observed in the previous follow-up studies. ... We conclude that Case ELGs give the high fraction of BCGs -- about 60 % of all galaxies with strong enough emission lines, and more than 40 % of all Case galaxies, marked with some code of the presence of [O III ] line. ...
