The field states the marker a saturated pixel carries, not the last valid count
an NXmx saturation_value states, so it is already the exclusive limit and must
not be raised by one. At the usual 65535 in a 16-bit image the limit became
65536, which no pixel can reach, and no marCCD pixel was ever called saturated.
On one open-arm Rayonix set that costs the space group: ~60k pixels per frame sit
at the marker in one detector block, at 1.37-1.65 A, and integrate as if they
were signal - I/sigma ~11 with CC1/2 ~0. The symmetry operators' correlations
drop below the 0.30 gate on that band alone, so the run merges in P1 and cuts at
1.65 A. With the limit right it is P 2 21 21 to 1.19 A with ISa 10.3.
The miniCBF path is left alone: there Count_cutoff is of order 1e6, so the same
one-count difference cannot reach a pixel.
