The pre-scan's beam-centre check and the post-refinement both measure where
the direct beam lands, but the report only carried the centre the run used.
Section 1 now sets the file's direct beam (FILE_DIRECT_BEAM) beside the
background's (BACKGROUND_DIRECT_BEAM, with its sigma), the shift of the
refined centre from the file's (BEAM_CENTRE_SHIFT) and the tolerance the
geometry asks for (BEAM_CENTRE_TOLERANCE: BeamCenterNeed_pxl, the number the
log's check prints, here on the run's own cell). A shift above the tolerance
is a BEAM_CENTRE_OFF warning naming the file's, refined and background
centres, the difference in px and mm and the value to correct the beamline
to; a run that refined no centre is warned on the background alone where
its fit resolves the difference (3 sigma). The summary gains a Beam centre
line.
The refined centre, not the background, is the trigger wherever one exists:
on a battery set where XDS's refined direct beam and rugnux's agree to 1 px,
the background fit is 12 px away from both. Report-only; no result changes.
