This directory contains solar EUV data from 1973 SKYLAB S-055
experiment. The data consist of both FITS data files and raw data
files, contained in two subdirectories: /fits_data and /raw_data. 

The subdirectory /fits_data contains fits data files created in 2012
by copying from CDs (Compact Disks) which were in turn written by
Mathieu Hirtzig at CfA in 2001 from SKYLAB-S055 data stored at the
time on tape at CfA.  These data are stored in 22 subdirectories
(/fits_data/CD01 through /fits_data/CD22), each of which is a copy of
one of the 22 CD's. Each of the subdirectories contains an identical
sub-subdirectory named /README_S055, which contains a number of files
some of which may be helpful in examining the data. It is recommended
that those unfamiliar with the S055 experiment look at the file
README_S055.txt for background, as well as other files in the
README_S055 sub-subdirectory, some of which provide useful auxilliary
information.

The subdirectory /raw_data contains the raw data from which the fits
data files were created.  This is probably of limited use, but is
included for archival purposes.
