  The aim of our paper is to make high-precision positional stellar catalogs by
compiling large astrophysical data bulk and large astrometrical surveys. The
data reliability and uniqueness is the primary request. The common precision of
1 arc sec in coordinates is insufficient now to guarantee the simple
identification of stars. Therefore the technique of catalogs verification
become relevant. The paper presents the outcome of stars identification in The
Henry Draper Extension Charts catalog and Variable stars catalog using proper
method. Examples of conflicts permission concerning doubles and multiples stars
in astrophysical catalogs are discussed.
