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 1981SSRv...28..227V, Cat. III/85)
- The BR number is from the catalogue by Breysacher (1981A&AS...43..203B 1981A&AS...43..203B)
- The AB number is from Azzopardi and Breysacher (1979A&A....75..120A 1979A&A....75..120A)
for stars in the Small Magellanic Cloud.
Note on Note:
a Lundstroem and Stenholm (1979A&AS...35..303L 1979A&AS...35..303L) quote that the b
magnitude of WR30 in Smith's paper (1968MNRAS.140..409S 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 1984A&A...140..459S)
d WR star discovered by Conti and Garmany (1983PASP...95..411C 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 1968MNRAS.140..409S
2 = Lundstroem and Stenholm (1979A&AS...35..303L 1979A&AS...35..303L)
3 = IRS data from Massey 1984ApJ...281..789M 1984ApJ...281..789M

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.
