Summary of the present status of the survey

Summarizing the results of the Hamburg/SAO survey presented in Papers I through V, we discovered altogether from the 1-st priority candidates 433 new emission-line objects (25 of them are QSOs), and for 85 known ELGs we got quantitative data for their emission lines. At the moment the total number of confident or probable blue compact/low-mass H II-galaxies reaches 360. Relative to all observed 493 ELGs the fraction of BCGs (360/493 or 73 %) demonstrates the high efficiency of the survey to find this type of galaxies. 21 more new BCGs and 20 other type ELGs are found among the second priority candidates. To estimate the total number of BCGs in the HSS zone we should count new BCGs expected from the remaining candidates and those selected in the HSS, but not observed by us since they already were known from other surveys. Thus we expect the total number of BCGs in this sky region to be $\sim$500. This will be the largest homogeneous BCG sample in both hemispheres.
