To improve the efficiency for the selection of BCGs among the second priority candidates we introduced additional selection criteria using the APM (Irwin [1998]) database. An analysis of the spectroscopic classifications of all objects from the random subsample resulted in the following conclusions:
Therefore, having in mind to develop a strategy to pick up as many as possible low-mass BCG/H II-galaxies in the HSS region, but accounting as well for a high enough detection rate, we created an subsample of second priority BCG candidates, which fulfill the following additional criteria:
Of 633 objects from the second priority list in the strip =35-40 80 candidates were selected by these criteria. Eleven candidates from this additional list were observed by snap-shot spectroscopy. All of them have turned out to be ELGs of various types. 3 of them are certain BCGs, and 4 more are probable BCG/H II-galaxies. They are listed in Table 3 and are marked with .
