The fifth list

As result we have 209 observed candidates preselected on HQS objective prism plates, of which 169 were first priority candidates and 40 were second priority ones. 166 objects (79 % from 209 objects) are found to be either ELGs (161), or quasars (5).

Of 161 ELGs 98 galaxies (61 %) were classified based on the character of their spectra and their luminosity as H II/BCGs or probable BCGs.

Two of them (HS 1213+3636A and HS 1311+3628) are low-mass neighbours/satellites of the dwarf spiral NGC 4214 and of the Im galaxy UGC 8303. As the discussion of the local environment of BCGs is out of the scope of this paper, we refer to a recent analysis of this issue by Pustilnik et al. ([2001]).

HS 1213+3636B and HS 1423+3945 are SAs in the dwarf spirals NGC 4214 and UGC 9242.

Six ELGs are difficult to classify at all due to their poor signal-to-noise spectra. Six more ELGs were classified as Active Galactic Nuclei (AGNs): 3 as Seyfert galaxies and 3 as LINERs. The remaining 49 ELGs are objects with low excitation: either starburst nuclei galaxies (SBN and probable SBN) or their lower mass analogs - dwarf amorphous nuclear starburst galaxies (DANS or probable DANS).

By keeping a high fraction of BCGs ($\sim$ 62 % among the first priority candidates) we continue to have a high efficiency of discovery new BCGs, which is the main goal of the HSS. Since the completeness of the BCG sample under construction is an important parameter for many follow-up statistical studies, we observed a randomly selected sample of candidates from our list of second priority candidates. As discussed already in Paper IV at most 10 % of them turned out to be BCGs. Using additional information from the APM is an efficient means to pick up these BCGs among the second priority candidates: among 23 objects observed 10 BCGs (43 %) were discovered (Table 1).
