Description:
   This data set contains 937 sets of spectrophotometric observations of
   stellar continuua made in the 3200-12000A region.  The data were
   transformed to the Hayes and Latham (1975) calibration of Alpha
   Lyrae. Bandpasses vary between 10 and 100A.  An analysis of the
   errors in the catalog appears in Breger (1976).  Note that scans of
   the southern stars observed by Gutierrez-Moreno et al. (1968) are
   NOT corrected for the right ascension effects discussed in Breger
   (1976).

Note on B-V:

  Star Catalogue or the original spectrophotometric source. 

Note on Mag:
  The magnitude refers to the conventional magnitude per unit frequency.
 
Remarks and Modifications:         
  The Catalog of Spectrophotometric Scans of Stars (Breger, M.
  1976, Ap.J. Supp., 32, 7.) was received in machine-readable form
  from Dr. S. Parsons (University of Texas) on March 11, 1976.
  The version as received consisted of a 7-track 800 bpi magnetic
  tape with two files.  The first file contained the analysis
  program as written for the CDC 6600 computer and the second file
  represents the original data.  The analysis program was then
  converted to run on the IBM S/360 at NASA/GSFC and the data was
  processed.  Some corrections to the original analysis program
  had to be made due to the differences in the computers, but since
  the result of the analysis was a listing of the data as given in
  the above reference - checks were possible at every step of the
  analysis.  The output was then reformatted so that the data would
  be in a format that allowed easy access to the data.  As the
  catalogue was checked out, a number of star name errata were noticed.
