Beside --beam-x/--beam-y/--detector-distance/--wavelength, the remaining metadata a foreign XFEL
file can get wrong are given on the command line rather than through a hand-built geometry file:
--pixel-size (um); --saturation (the pixel value from which a pixel is overloaded, in the units
the frames are read in), which also replaces the level stills read off the frames; and --gain
(detector units per photon), for CXI and --crystfel-geometry input, whose reader converts the
frames to photons with it - refused for other inputs, which are read in the units they state.
Single-panel Rayonix CXI, 1316 frames, -C/-S, --detector-distance 105: --gain 0.37 (the pre-scan's
background measurement) gives rugnux R-free 0.344 against 0.358 in detector units.
