Science Monthly Minimum background image data from the Compact Coronagraph-1 (CCOR-1) aboard the GOES-19 spacecraft, produced by the NOAA NCEI retrospective science processing pipeline. Each background image is generated by calculating the pixel-wise minimum of a set of Science Daily Median images over a multi-day interval. The data are provided in FITS format as 2048 by 1920 pixel intensity arrays expressed in mean solar brightness (MSB), accompanied by pixel quality flag masks and a list of input Daily Median filenames. The Monthly Minimum images are generated daily and are used as background images for subsequent Level 2 processing. The nominal cadence is one image per day.

CCOR-1 Science Monthly Minimum white-light coronal background intensity stored in FITS extension #1 as a 2048 x 1920 pixel compressed 32-bit floating-point image array. The background image is calculated as the pixel-wise minimum of a set of Science Daily Median images over a multi-day interval and is expressed in mean solar brightness (MSB). The image uses helioprojective solar coordinates with a zenithal polynomial (ZPN) projection and a plate scale of approximately 19.33 arcsec per pixel at the reference point. The CCOR-1 bandpass has a measured full width at half maximum (FWHM) of approximately 470 to 740 nm. The DATE-BEG and DATE-END FITS keywords specify the observation interval covered by the input images, while DATE-OBS specifies the observation time of the reference image used for WCS metadata.
Pixel quality flag mask associated with the Science Monthly Minimum background intensity image in FITS extension #1. The mask is stored in FITS extension #2 as a 2048 x 1920 pixel compressed 8-bit integer array. Quality flags identify viable pixels, low-vignetting regions, non-transmitted image blocks, and invalid Monthly Minimum pixels with zero, NaN, or infinite intensity values. Flag definitions are provided in the FITS header.
FITS binary table containing the filenames of the Science Daily Median images used to calculate the Science Monthly Minimum background image. The table includes an index and source image filename for each input. The number of input Daily Median images may vary depending on data availability.
