Description:
The catalog is an objective-prism survey for stars of spectral classes
F2 to G5 in a region of high galactic latitude. The catalog contains
1127 stars and is complete to a limiting photographic magnitude of
12.5. The photographic plates used permit a separation of the stars
into narrow and well-defined spectral classes. The spectral
classification of the stars in the catalog is based on the Yerkes MK
system. The catalog is subdivided into one-degree declination zones as
are the DM catalogs. The degree zones are based on 1855 coordinates.
The catalog includes sequence numbers of the stars, BD and HD numbers,
positions (B1950), B magnitudes, spectral types, and remarks.

Note (1):
There is a <Null> value in column 'B' on line 1054 of which UI number
is 41 101. This star is observed on two deep plates, 4765 and 5471, taken
over one year apart, to be of spectral classes F2 and A5, respectively, and
magnitudes 12.6 and 12.1, respectively, and is not included in the list by
Slettebak and Stock (1959). The A5 spectral image appears similar to one of
RR Lyrae of the same dispersion (Nassau and Stephenson 1960). It is likely
that this star is a previously undiscovered RR Lyrae type variable.

History:
* 1971: the catalog was prepared by A.R. Upgren on punched cards
(see 1971BICDS...1...23. 1971BICDS...1...23.)
* 1988 June, Wayne H. Warren:
Data format modified at the Astronomical Data Center (ADC)/NASA GSFC,
* 2015-Dec, B. Skiff [Lowell Obs.]:
file "position.dat" contains the accurate position, from an
inspection of the finding charts. The star UI +32 31, missing in
the previous version, was added.
