The image dimensions may vary between files. The FITS header provides helioprojective longitude and latitude coordinates with a CAR projection and an alternate ICRS right ascension and declination coordinate system. The pixel scale is 0.02 degrees, or 72 arcsec, at the reference point. The nominal wavelength is 530 nm. The reference time of the model is specified by the DATE-OBS FITS keyword. 2.009e+07 W m^-2 sr^-1 Electromagnetic Intensity 530 530 nm FITS Extension #2 Inverse Fractional Uncertainty Inverse fractional uncertainty associated with the unpolarized brightness in the PUNCH Level 3 CSM starfield model. The stored value is the brightness divided by its uncertainty. The data are stored in FITS extension 2; the FITS EXTNAME is "UNCERTAINTY ARRAY". Dimensionless Uncertainty Other
