Limited magnitude range in DynPSF

Siril version: 1.4.0

Note: please report against latest git master branch or latest stable version

Operating System: [Windows? macOS? Linux?] W11

Package: [tell us where from]

Description of the bug

The mag shown after a DynPSF analysis exhibits a too limited range (here, about 4 mag). The fainter stars are not usable for further analysis

Dynamic PSF view sorted in descending order of magnitude

The same analysis sorted in ascending order of magnitudes

As an illustration, a calibration curve exhibits a strange bended shape in the higher magnitudes, as shown:

Expected result: A wider range for the calculated magnitudes, even if the mag in the DynPSF is an estimated value (with uncertaity). That would make the output file of the DynPSF usable for magnitude calibration.
