lsst.meas.algorithms.htmIndexer.HtmIndexer.getShardIds | ( | self, | |
ctrCoord, | |||
radius ) |
Get the IDs of all shards that touch a circular aperture. Parameters ---------- ctrCoord : `lsst.geom.SpherePoint` ICRS center of search region. radius : `lsst.geom.Angle` Radius of search region. Returns ------- results : `tuple` A tuple containing: - shardIdList : `list` of `int` List of shard IDs - isOnBoundary : `list` of `bool` For each shard in ``shardIdList`` is the shard on the boundary (not fully enclosed by the search region)?
