“tiles ok” is not a tolerance. measure_offset_grid runs with no
max_off_mas, and astrometry_offsets sets
off_ok=True whenever that is None — so N/N counts tiles
whose offset histogram had a coherent peak, however large the offset.
The column that carries the gate is worst tile, against
15 mas.

F115W_o001: 5/32 exposures misaligned vs their visit consensusAn exposure is misaligned when its offset exceeds 2.0 mas AND is significant against the peak error bars. At m2 this CORRECTS the offsets table and stops the run; the crf frames must be regenerated before cataloging continues.checkpoint_m2_F115W_o001_latest.json
what is affected, and why
Affected: 3/8 detectors — spread across detectors, so the frame as a whole moved: look at the offsets table and whether these exposures were regenerated from _cal after the table changed. fix_alignment SKIPS a frame that already has a RAOFFSET header, so correcting the table alone leaves stale frames in place; regenerate the working copy from _cal instead of re-applying on top.Per-exposure offset vectors, coloured by detector. Solid = flagged misaligned. One colour pointing away means one detector; everything fanning out means the frame moved.
