PUNCH Level 3 clear K-corona science mosaic (trefoil) images in the clear polarization state. The images are background-subtracted, including F-corona and starfield subtraction, and resolved into unpolarized brightness (B) with uncertainty.
This dataset is a member of the Collection of PUNCH Level-3 Science Image dataset. Per instructions from the PUNCH team, reference to the entire Collection (including the DOI, see below) should be used when this and other member datasets in the Collection are needed for citation purposes: Southwest Research Institute (2025).

Unpolarized K-corona brightness in the PUNCH Level 3 CTM composite mosaic, provided in output coordinates. The data are stored in FITS extension 1 as a 4096 x 4096 image; the FITS EXTNAME is "PRIMARY DATA ARRAY".
Inverse fractional uncertainty associated with the unpolarized K-corona brightness in the PUNCH Level 3 CTM composite mosaic. The stored value is the brightness divided by its uncertainty. The data are stored in FITS extension 2 as a 4096 x 4096 image; the FITS EXTNAME is "UNCERTAINTY ARRAY".
