hipscat.catalog.healpix_dataset.healpix_dataset.HealpixDatasetA HiPSCat Catalog used to contain the ‘margin’ of another HiPSCat catalog.
Catalogs of this type are used alongside a primary catalog, and contains the margin points for each HEALPix pixel - any points that are within a certain distance from the HEALPix pixel boundary. This is used to ensure spatial operations such as crossmatching can be performed efficiently while maintaining accuracy.
