BEAM_CENTRE is the PONI - the foot of the perpendicular from the sample - so on a
tilted detector it is not where the direct beam lands. The report printed only that
one number and never mentioned the tilt at all, so the two points were
indistinguishable to a reader. On a detector at 85 mm with a 0.22 degree tilt they
are 8.3 px apart.
Print DETECTOR_TILT (rot1/rot2/rot3, degrees, as the run used them - nothing is
refined here) and DIRECT_BEAM beside BEAM_CENTRE, and say which is which.
JFJOCH_DATASET_SETTINGS was the more serious half: it exists to carry a geometry
back into the instrument, and dataset_settings carries poni_rot1/2/3_rad, but the
block omitted them - so it described a FLAT detector, silently, on every tilted
setup. The rotations now ride with it when they are non-zero; they stay out when
they are zero, because the API's own default is 0.0 and the shorter block means the
same thing.
