*****  File ATLSINFO.TXT                                                                                   This information file is located in the SOL_ATLS subdirectory of the\DOCUMENT\APPENDIX directory.      Two high resolution integrated disk solar spectra compiled from a varietyof sources are presented in this directory.  One was contributed by M. A'Hearnand the other by R. Kurucz.  The A'Hearn solar spectrum found in one file,SOLATLS1.FIT, is given in vacuum wavelengths (Angstrom units), calibrated influx units (erg/cm**2/s/A) covering the wavelength range 2245 A to 7000 A  insteps of 0.005 A.  The Kurucz solar spectrum can be found in two files,SOLATLS2.FIT AND SOLATLS3.FIT, in air wavelengths (Angstrom units), calibratedin flux units (erg/cm**2/s/A).  SOLATLS2.FIT covers a wavelength range 2960 Ato 8000 A in steps of 0.005 A. SOLATLS3.FIT covers the wavelength range 8000 Ato 13,000 A in steps of 0.01 A.  We note a wavelength shift between the twosolar spectra presented in this archive of approximately 0.03 A in the senseA'Hearn minus Kurucz.  We therfore caution users of these files requiringwavelength accuracies better than this difference to first assess and correctthe wavelengths of the solar spectra to a rest frame.

The data are one dimensional spectra.
