Parameter #1
Name
FITS Extension #1 Brightness Data Array
Description
PUNCH Level 3 polarized K-corona mosaic stored as a compressed three-dimensional floating-point image cube with three image layers: total brightness (B), polarized brightness (pB), and the conjugate polarized brightness component (pB'). The data array dimensions are 4096 x 4096 x 3. The FITS header provides helioprojective longitude and latitude coordinates with an ARC projection and an alternate ICRS right ascension and declination coordinate system with a STOKES third axis. The pixel scale is 0.0225 degrees, or 81 arcsec, at the reference point. The nominal wavelength is 530 nm. The reference time is specified by the DATE-OBS FITS keyword.
