The First Byurakan Survey (fbs) and Search Problems for AGN
Abstract
The history of the First Byurakan Survey carried out to search for AGN is shortly described. The sample completeness for different classes of objects: Sy1, Sy2, QSO, BL Lac objects is estimated as 0.6, 0.4, 0.4 and 0.6, respectively. The lack of radioquiet BL Lac objects as a whole class is shown. Different search procedures of AGN are compared, their perspectives are evaluated.
