Description:
The catalog is intended to list all 5987 cool carbon stars having known
positions of at least roughly the precision of The Henry Draper
Catalogue. Cool carbon stars are defined as stars whose spectra at low
dispersion (say a resolution no better than 1-2 angstroms) are known
to show bands of the Swan system of the C2 molecule; or, if the
spectral region of the Swan system is inadequately observed, they show
the red or infrared bands of CN in strength adequate to infer that the
Swan bands almost certainly would be seen if their presence could be
tested. The closing date for literature search was 1989 June 30,
defined by literature received in the author's library by that date.
The catalog includes equatorial coordinates (B1900.0); photographic,
visual, and infrared magnitudes; spectral types, galactic coordinates,
and cross identifications to various other designation systems.

Remarks and Modifications:
* Star #364 was found to have an incorrect declination in both the
published and machine-readable catalogs. The latter has been corrected
in both declination and galactic coordinates...WHW/ADC 3/1991.
* Star #4942 was erroneously typed 4972 (FO/CDS, 1997/01)
