Direct sheets are anchored to surviving control points; adjacent sheets tie-registered through their shared overlap. Affine fit in EPSG:3857; RMSE in meters.
Trinity Church is the first control point in the Sheet 10 file: 40.70807° N, 74.01187° W.
Each file lists the source-image pixel coordinates and WGS-84 lat/lng of every control point, the fitted affine transform, and its RMSE — enough to reproduce or independently check the placement.
