“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.

F212N visit 1: worst tile 20.7 mas at cell (1,2) (> 15 mas)36/36 tiles are reported "ok", but that counts tiles whose offset histogram had a coherent PEAK — not tiles within tolerance. The m7 cross-band gate is no significant 2" cell above 15 mas, and this cell exceeds it, so the bulk tie being ~0 does not mean the field is flat.checkpoint_m2_F212N_latest.json
what is affected, and why
9/36 cells exceed 15 mas. They are not confined to the edge, so this is an interior residual: a distortion or per-detector alignment problem, not a coverage artefact. The bulk tie for this visit is 1.02 mas — a small bulk value cannot cancel a local one.Per-tile residual across the mosaic. Outlined cells exceed tolerance; the circled cell is the worst.
