Description
Science Level 2 image data from the Compact Coronagraph-1 (CCOR-1) aboard the GOES-19 spacecraft, produced by the NOAA NCEI retrospective science processing pipeline. The data consist of calibrated white-light coronagraph images of the solar corona with background subtraction using Science Monthly Minimum images. The images are provided in FITS format as 2048 by 1920 pixel intensity arrays expressed in mean solar brightness (MSB), accompanied by pixel quality flag masks. The Monthly Minimum background is calculated from Science Daily Median images and subtracted to enhance transient coronal structures such as coronal mass ejections (CMEs). The nominal cadence is approximately 15 minutes. These science products are distinct from the operational Level 2 products.

Parameter #1
Name
FITS Extension #1 Background-Subtracted White-Light Coronal Intensity Data Array
Description
CCOR-1 Science Level 2 white-light coronal intensity stored in FITS extension #1 as a 2048 x 1920 pixel compressed 32-bit floating-point image array. The image is generated by subtracting a Science Monthly Minimum background image from a calibrated coronagraph image 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 reference time is specified by the DATE-OBS FITS keyword.

Parameter #2
Name
FITS Extension #2 Pixel Quality Flag Mask
Description
Pixel quality flag mask associated with the Science Level 2 coronal 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, pixels below the detector linear range, correctable nonlinear response, saturated pixels, unreliable photometry, dead pixels or data downlink failures, and invalid pixels associated with Daily Median or Monthly Minimum background processing. Flag definitions are provided in the FITS header.
