Description:
This catalogue contains data on 318 cool carbon stars discovered
on objective prism photographs taken with the Schmidt Telescope
(80/120/240 cm) of the Radioastrophysical Observatory at Baldone
near Riga.
Green-yellow survey (BC Nos 1-217) is made on the ortochromatic
astronomical films A-600. Reciprocial dispersion of the spectra:
600 A/mm or 1130 A/mm at H-gamma.
The region of the sky covered by the survey:
1) 4.5 degrees wide zones centered on the galactic latitudes
+7 and -7 degrees between longitudes 68 and 200 degrees,
2) equatorial zone at longitudes 84-96 degrees and 172-180 degrees,
3) several other separate fields with five degrees diameter.
Infrared survey (BC Nos 218-318) made on the infrared Kodak plates
1N with the filter Schott RG1. Reciprocial dispersion: 2500 A/mm
at the atmospheric A-band. The region of the sky covered:
1) 4.5 degrees wide zone centered on the galactic latitude +7
degrees between longitudes 128 and 140 degrees,
2) region between latitudes +9.5 and -9.5 degrees and longitudes
between 80 and 96 degrees.

Note (1): position as measured on direct red plates taken with the
Schmidt Telescope and reduced using the AGK3 catalogue.
Note (2): the spectral classification (late R or early N) depends on
density distribution of obtained spectra, thus the faint
Carbon stars are denoted by C.
Note (3): the symbol "(" indicates an upper limit of brightness in the
case of extremely faint stars.
Note (4): photographic red magnitude, effective wavelength 0.63 microns.
Note (5): Cross-identification between this catalogue and the others.
The number of the star is given in cols. 103-106, and the
appropriate reference, coded according to the References
below, in cols. 108-109.
