Description:
Continuing the survey for faint blue stars at high galactic latitudes
of Haro and Luyten (1962, Cat. III/74, this search was made,
following the Tonantzintla three image method, with the 48" Schmidt
telescope of Mt. Palomar. In the first paper, a catalogue of 4431
stars and 84 compact objects found in nine PSS fields scattered around
the NGP is presented, with the 1950 positions and the estimated
magnitudes and colour classes. The catalogue contains also extensive
identifications with previous surveys, including some known QSSs; 16
QSS candidates are proposed; spectra are available for most of the
unknown stars brighter than 14mag.
In the second paper, a catalogue of 2011 stars and compact objects is
presented with the 1950 positions and the estimated magnitude and
colour classes. Complementary to the catalogue of Haro and Luyten
(1962BITon...3...37H 1962BITon...3...37H) at declination +6° and 0° it contains
also extensive identifications with previous surveys and known QSO's;
candidate QSO's are indicated; spectra are available for some new blue
stars.
The third and last part of the survey of faint blue objects contains a
catalogue of 2484 starlike or compact objects is presented with the
1950 positions, estimated magnitudes, color classes and extensive
identifications with stars of previous surveys and known QSO's.
The three parts were merged into a single file "catalog.dat".
