         <Description>Science-quality retrospective Level 2 image data from the Compact Coronagraph-2 (CCOR-2) aboard the SOLAR-1 spacecraft. The data consist of background-subtracted white-light coronagraph images of the solar corona generated from Science Level 1A data using a CCOR-2 monthly minimum background image. The images have dimensions of 2048 by 1920 pixels and are provided in FITS format in units of mean solar brightness (MSB). The nominal data cadence is approximately 15 minutes.</Description>

         <Name>FITS Extension #1 Monthly-Minimum-Subtracted White-Light Coronal Intensity Data Array</Name>
         <Description>CCOR-2 Science Level 2 background-subtracted white-light coronal intensity stored in FITS extension #1 as a 2048 x 1920 pixel compressed floating-point image array. The Level 2 image is generated from Science Level 1A data by subtracting a CCOR-2 monthly minimum background image. The image is expressed in mean solar brightness (MSB) and uses helioprojective solar coordinates with a zenithal polynomial (ZPN) projection. The plate scale is approximately 24.27 arcsec per pixel at the reference point. The reference observation time is specified by the DATE-OBS FITS keyword.</Description>
