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.
