This version of ``An Atlas of the Photospheric Spectrum from 8900 to 13600 
cm-1 (7350 to 11230A)'' (N.S.O. Technical Report #93-001, April 1993) by
L. Wallace, K. Hinkle, and W. Livingston, is meant to be used in conjunction 
with the original hard-copy version, and the caveats in the text of that 
version apply here equally.

The three spectra on each page of the original are combined into one ascii file
covering the main 25 cm-1 of the page plus 2 cm-1 of overlap on each end.  
Each file is given the name ``phxxxxx'' where xxxxx is the wavenumber of the 
beginning of the main 25 cm-1 of the page.  Thus, ph10050 contains the material
from 10050 to 10075 cm-1 plus 2 cm-1 of overlap on each end.  The first column
contains the wavenumber while the second, third and fourth contain the solar
component, the atmospheric component and the observed 1.0 air mass spectrum, 
respectively.

The spectra have been processed so that no adjustment has been made in these
files to set the continuum levels at approximately unity; the intensity level
in each file is continuous with that in the adjacent files.  For convenience,
however, the first line in each file contains, centered over the second,
third, and fourth columns, approximate continuum levels appropriate to these
spectra in the frequency range of the file.  The subsequent 4096 lines of
each file contain the spectra.  In the worst places of low signal-to-noise,
the regions have been filled with -1.0, but some regions which show gaps
in the hard-copy version will show noise here.
