FITS at a glance
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.
MIFF at a glance
MIFF
MIFF reflects the older tradition of image-processing toolkits defining their own native technical formats for fidelity and internal workflow convenience.
