Results of follow-up spectroscopy

In Table 1 we present the results of the observations. The 209 candidates were selected from our first and second priority samples introduced in Paper IV.

Of 169 first priority candidates, 141 objects appeared in our list as new ones. 28 objects were listed in the NED as galaxies or objects from various catalogs with known redshifts and some of them already had information on emission lines in earlier publications. All objects were included in our observing program in order to improve spectral information. Comparison of our velocities with those of galaxies with already known redshift shows acceptable consistency within the uncertainties given.

Another 40 candidates observed were taken from the list of second priority candidates. As described in Paper IV two samples were created from this list. A ``random selected sample'' containing randomly selected objects from the list and the ``APM selected sample'' which uses additional information for selection. The ``random selected sample'' was created to access the fraction of BCGs in the second priority list and contains 43 objects. For 26 of them the spectral data were presented in Paper IV, while for the remaining 17 candidates observed with the CAHA 2.2m telescope, the spectral information is presented here. The results of the analysis for this sample were presented in Paper IV. We found that the second priority list contains at most 10% BCG/H II-galaxies.

The second, ``APM selected'' sample comprises second priority candidates which are classified as non-stellar on Palomar Sky Survey plates (PSS) in the APM database, and have blue color according to the APM color system ((B-R) < 1.0). Here we give spectral data for 23 objects from this sample. Except one all are ELGs confirming the efficiency of this selection criterium to pick up the BCG/H II-galaxies from the second priority list (cf. Paper IV).
