Abstract:
    Accurate positions and charts for 1707 carbon stars in the Small
    Magellanic Cloud identified on GRISM plates are presented. The catalog
    provides data on magnitudes, colors, and carbon-abundance measurements
    and can be used for selecting carbon stars with special
    characteristics.

  44- 45  I2    0.1nm   C2(EW)    ? Equivalent width of the C2 band
                                    at 516.5nm, measured between the peaks in
                                    the spectra at 485 and 522nm
      46  A1    ---     u_C2(EW)  Uncertainty flag (:) on C2(EW)

  73- 88  A16   ---     Ident     Other cross-identifications (2)

Note (1): remarks are numbered as follows:
   1= Doubtful C star
   2= spectrophotometry not possible because of overlapping spectra
   3= spectrophotometry not possible because of underexposed spectrum
   4= spectrophotometry not possible because of overexposed spectrum
   5= very red carbon star
   6= very faint carbon star in field A or B and detected at a late stage
        in the survey by E. Rebeirot
   7= medium resolution slit spectroscopy available
   8= IR photometry in the Johnson JHK system available
