PUNCH Clear science mosaics (Trefoil) in output coordinates, resolved into image and uncertainty layer.
These are rectified NFI images and full-constellation mosaic trefoil images, resampled to output projection coordinates (gnomonic projection for NFI and azimuthal-equidistant projection for the mosaics). Polarization is given in the virtual-polarizer M,Z,P system. The images are intended to be photometric, astrometrically regularized images of the celestial sphere with all light sources included.
