Description of the tape by Robert Kurucz:
This tape lists fluxes and temperature-mass relations for 1200 models.
The first 284 models are from Kurucz, R.L., Ap.J. Supp., 40,1,1979 and
are described there. Next are purely radiactive models for A and B stars
with Teff 8000K to 20000K for [M/H] =-1.,-.5,+.5,+1. Finally 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
I am computing visible and infrared colors in various photometric
systems, these new fluxes should not be used to publish colors
without my agreement. For any other use these fluxes are in the
public domain.
The models are presented as ATLAS format input decks.
The tape is recorded on 9 tracks at 1600 bpi in ASCII card images
with 4000 character blocks. A sample program that reads the tape
follows. I suggest that the user read the tape once and write
a binary tape that can be read much more quickly.
Program to read the tape:

Parameters from Table 6 and Table 4
See the enclosed note.tex (standard latex) for units in Table 6.
The enclosed program readfile.f (standard f77) based on the
above program reads the input file (assumed logical unit 5)
and prints the values from Table 6 and headers of Table 4
A file (grid) which contains the basic parameters of the the 1200
models has been directly created from the main file.
