VI/39       Model Atmospheres for G,F,A,B,O Stars (Kurucz 1979)

Description:
  This catalog lists fluxes and temperature-mass relations for 1200
  models. The first 284 models are from Kurucz, R.L., Ap.J. Supp., 40,
  1, 1979. Next 325 models are purely radiative models for A and B stars
  with Teff 8000K to 20000K for the metallicity/hydrogen abundance 
  ratios (in log10 scale), [M/H] = -1., -.5, +.5, +1. Finally the last
  591 models are new improved convective models for 5500K to 8500K with
  [M/H]= +1., +.5,0., -.5, -1., -1.5, -2., -2.5, -3., -9.99. Because the
  new models have not yet been published and because Dr. Kurucz is
  computing visible and infrared colors in various photometric systems,
  these new fluxes should not be used to publish colors without his
  agreement (Kurucz 1993, private communications). 

  The data in this catalog are very outdated. Dr. Kurucz is sending the 
  ADC an updated version while he works on an up-to-date version. He has 
  an extensive amount of data available and distributes them on CD-ROM.
  Email kurucz@cfa.harvard.edu for details.

Remarks and Modifications:
  To retrieve information from the original data file 'main' easier, we 
  split this 'main' file into two tables, table4.dat and table6.dat. 
  They contain similar data columns as tables 4 and 6 of Kurucz 
  (1979), respectively. And we create two standard Fortran codes to 
  read these catalog data files.
  See the enclosed note.tex (standard latex) for units in table6.dat. 
  A file (grid), models, which contains the basic parameters of the the 1200
  models has been directly created from the catalog data files.

Acknowledgments:
  There was no previous ADC documentation and a brief description (Intro)
  by CDS (1993) was used to create this ReadMe file.
