compare_sky_projection_to_legacy_wcs

lsst.images.tests.compare_sky_projection_to_legacy_wcs(sky_projection, legacy_wcs, pixel_frame, subimage_bbox, is_fits=False)

Test a Projection object by comparing it to an equivalent lsst.afw.geom.SkyWcs.

Parameters:

• sky_projection (SkyProjection[TypeVar(F, bound= Frame)]) – Projection to test.

• legacy_wcs (lsst.afw.geom.SkyWcs) – Equivalent legacy WCS.

• pixel_frame (TypeVar(F, bound= Frame)) – Expected pixel frame for the sky_projection.

• subimage_bbox (Box) – Bounding box of points to generate for tests.

• is_fits (bool, default: False) – Whether this sky_projection is expected to be exactly representable as a FITS WCS. If False it is assumed to have a FITS approximation attached instead.

Return type:

None
