get_legacy_non_cell_coadd_mask_planes

lsst.images.get_legacy_non_cell_coadd_mask_planes() → dict[str, MaskPlane]

Return a mapping from legacy mask plane name to MaskPlane instance for LSST non-cell coadds such as template_coadd in DP2, and all DP1 coadds.

These coadds carry the visit-level planes propagated from their input warps in addition to the coadd-specific planes, and flag chip edges with SENSOR_EDGE (cell coadds use CELL_EDGE instead).
