Description
Science-quality retrospective daily median image data from the Compact Coronagraph-2 (CCOR-2) aboard the SOLAR-1 spacecraft. Each daily median image is generated from Science Level 1A white-light coronagraph images acquired during one UTC day. Nominally, 96 Level 1A images at approximately 15-minute cadence are combined to produce one daily median 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 one day.

FITS Extension #1 Daily Median White-Light Coronal Intensity Data Array
Description
CCOR-2 Science Daily Median white-light coronal intensity stored in FITS extension #1 as a 2048 x 1920 pixel compressed floating-point image array. Each image is generated by calculating the daily median from Science Level 1A images acquired during one UTC day, nominally using 96 Level 1A images. 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 WCS pointing metadata and spacecraft location are approximate and are inherited from the middle Level 1A file in the stack of input files.
