Technical note

What changes when you convert FIT to PSD

A scientific camera records 32 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while PSD shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the PSD output as something to look at and publish rather than something to measure.
