PGM Raw in het kort
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.
FITS in het kort
FITS
FITS became a durable scientific standard because observatories, spacecraft, and analysis tools needed a stable interchange format that outlived individual instruments and software stacks.
