III/156     Cool Galactic Carbon Stars, 2nd Edition (Stephenson 1989)

A General Catalog of Cool Galactic Carbon Stars, 2nd edition Stephenson C.B. <Publ. Warner & Swasey Obs., 3, No. 2 (1989)> =1989PW&SO...3...53S
ADC_Keywords: Stars, carbon 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.

Note on RAh, RAm, RAs: The notes to Table 2 (table2.dat) are referenced by right ascension.
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) Acknowledgements: The ADC Intro file provided by C. B. Stephenson (1989) together with the description file by Wayne H. Warren (1991) were used to create this ReadMe file.
