ATLAS12      opacity sampling model atmosphere program.  Preliminary
             version that still uses ATLAS9 equation of state so 
             cannot do depth dependent abundances or isotopes
ATLAS9       model atmosphere program with opacity distribution functions.
             Extensions ending in CD are from CD-ROM 13.  Other files 
             are probably more recent versions.
BALMER       computes Balmer line profiles
COLORS       programs for computing colors.  Many need revision.
NEWDF        New version of distribution function program for workstations
OPACITY      Opacity miscellany
PARTFN       Partition function miscellany
SYNTHE       Current version of spectrum synthesis program SYNTHE 
             including He I lines but not yet including atmospheric transmission.  
        
SYNTHECD     Spectrum synthesis program SYNTHE from CD-ROM 18  
SYNTHENLTE   Version of SYNTHE that can read Avrett's models with departure
             coefficients and generate a spectrum that is non-LTE  for
             atoms treated in non-LTE and approximate for the rest.
UTILITIES    utilities
WIDTH        abundance analysis program
