Description:
    The catalog contains spectrophotometry at approximately 10-Angstrom
    resolution for 173 southern Wolf-Rayet stars. All observations were
    made at the Cerro Tololo Inter-American Observatory between November
    1981 and February 1985 with SIT-vidicon detector. The catalog includes
    synthetic photometry, and fluxes in the range 3400-7300 Angstroms for
    most known Wolf-Rayet stars in the Large Magellanic Cloud and in the
    range 3400-4700 Angstroms for all known Wolf-Rayet stars in the Small
    Magellanic Cloud.

Note on Star:
   - The WR number is from the catalogue by van der Hucht et al.
     (1981SSRv...28..227V, Cat. III/85)
   - The BR number is from the catalogue by Breysacher (1981A&AS...43..203B)
   - The AB number is from Azzopardi and Breysacher (1979A&A....75..120A)
     for stars in the Small Magellanic Cloud.
Note on Note:
   a Lundstroem and Stenholm (1979A&AS...35..303L) quote that the b
     magnitude of WR30 in Smith's paper (1968MNRAS.140..409S) should
     read 12.00, not 13.00
   b Includes visual companion, thus we give +ABS
   c Variable star (Stahl et al. 1984A&A...140..459S)
   d WR star discovered by Conti and Garmany (1983PASP...95..411C)
   e Close visual binary
   f Observations taken at air masses > 1.5
Note on vmag, u-b, b-v, v-r:
   The uvbr filters have central wavelengths and FWHM in nm:
   u: 365 (10)
   b: 427 ( 7)
   v: 516 (13)
   r: 600 (10)
Note on Qual: this index takes the values:
   1 = "best" data (absolute errors < 10%)
   2 = only one photometric observation
   3 = no photometric observation available, magnitudes can be wrong
         by up to 2 mag, but colors are still of use.
   4 = suspected variability
Note on Ref: the references are:
   1 = Smith 1968MNRAS.140..409S
   2 = Lundstroem and Stenholm (1979A&AS...35..303L)
   3 = IRS data from Massey 1984ApJ...281..789M
   4 = Lundstroem and Stenholm 1984A&AS...58..163L
   5 = Massey and Conti 1983ApJ...264..126M
   6 = Westerlund 1966ApJ...145..724W
Note on spFile, lam0, Dlam, Np:
  These values are present with the spectrum is exists (in subdirectory "sp").
  Each spectrum contains the wavelength and the flux in 2 columns as
  described below in the "Description of sp/* files" section

History:

  * May 1989 (from the "Documentation of Spectrophotometry of
    Wolf-Rayet Stars" by Anne C. Raugh):
    The spectra were received by the Astronomical Data Center (ADC), NASA
    Goddard Space Flight Center, from Dr A. V. Torres-Dodgen in February
    1988 as 174 separate text files stored on a VAX disk. These files were
    contatenated into a single file with 8 fluxes per line.

  * July 1999 (Francois Ochsenbein, CDS): data from table1 of the
    publication were added, positions of the stars were added, using
    the SIMBAD data-base, and the documentation file (ReadMe) was added.
