Technical note

FITS to PCX: what carries over and what does not

A scientific camera records 32 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while PCX shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the PCX output as something to look at and publish rather than something to measure. PCX stores a limited palette rather than full colour, so the conversion has to reduce the number of distinct colours. Photographic content shows this as banding, while flat graphics and icons usually survive it untouched.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
