SY Science-quality retrospective Level 3 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 2 data by downsampling the images by a factor of two along each image axis. The images have dimensions of 1024 by 960 pixels and are provided in FITS format in units of mean solar brightness (MSB). The nominal data cadence is approximately 15 minutes.

The Level 3 image is generated from Science Level 2 data by downsampling the image by a factor of two along each image axis. 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 48.55 arcsec per pixel at the reference point. The reference observation time is specified by the DATE-OBS FITS keyword.
