Trims three opt-in stills parameters that did not improve data quality on the
external-reference (PDB R-free) battery and only added code:
- --partiality-uncertainty: the (1-p)/p merge-sigma term was null on all four
serial-stills datasets of the battery vs their reference structures (and
neutral-to-harmful at higher coefficients); removed the flag, setting and
CorrectedSigma term.
- --stills-modulation: the detector-plane flat-field surface was net-negative
on flooded data; removed the flag, setting and MergeOnTheFly::RefineModulation
(the rotation modulation in RotationScaleMerge is unaffected).
- --min-indexed-fraction: every value other than the 0.20 default collapsed
CC1/2; removed the override flag/setter, keeping the fixed 0.20 acceptance
floor.
Default behaviour is unchanged (all three were off / at their default).
