      <Description>This data set contains Skylab SO-52 whitelight coronagraph FITS images, as originally posted at UCAR/HAO. Four types of data are provided: intensity of the corona in B/Bsun units, alpha-angle data, polarization data, and polarization brightness data. The data have been corrected for Earths elliptic orbit around the sun.</Description>
      <Acknowledgement>The assistance of Dr. O.C. St. Cyr at NASA Goddard Space Flight Center is gratefully acknowledged in supplying SPDF with a copy of these data.</Acknowledgement>
