ConfigClass = RingsSkyMapConfig | |
Rings sky map pixelization. We divide the sphere into N rings of Declination, plus the two polar caps, which sets the size of the individual tracts. The rings are divided in RA into an integral number of tracts of this size; this division is made at the Declination closest to zero so as to ensure full overlap. Rings are numbered in the rings from south to north. The south pole cap is ``tract=0``, then the tract at ``raStart`` in the southernmost ring is ``tract=1``. Numbering continues (in the positive RA direction) around that ring and then continues in the same fashion with the next ring north, and so on until all reaching the north pole cap, which is ``tract=len(skymap) - 1``. However, ``version=0`` had a bug in the numbering of the tracts: the first and last tracts in the first (southernmost) ring were identical, and the first tract in the last (northernmost) ring was missing. When using ``version=0``, these tracts remain missing in order to preserve the numbering scheme. Parameters ---------- config : `lsst.skymap.RingsSkyMapConfig` The configuration for this SkyMap. version : `int`, optional Software version of this class, to retain compatibility with old verisons. ``version=0`` covers the period from first implementation until DM-14809, at which point bugs were identified in the numbering of tracts (affecting only tracts at RA=0). ``version=1`` uses the post-DM-14809 tract numbering.

To support pickling. Notes ----- **Warning:** This method assumes that the constructor is be defined: __init__(self, config, version=defaultVersion) The use of 'config' is effectively set by the registry mechanism. If additional optional arguments are added, this method should be overridden to correspond.

Find all tracts which include the specified coord. Parameters ---------- coord : `lsst.geom.SpherePoint` ICRS sky coordinate to search for. Returns ------- tractList : `list` of `TractInfo` The tracts which include the specified coord.

Find closest tract and patches that overlap coordinates. Parameters ---------- coordList : `lsst.geom.SpherePoint` List of ICRS sky coordinates to search for. Returns ------- retList : `list` list of (TractInfo, list of PatchInfo) for tracts and patches that contain, or may contain, the specified region. The list will be empty if there is no overlap.

def lsst.skymap.ringsSkyMap.RingsSkyMap.getRingIndices | ( | self, | |
index | |||

Calculate ring indices given a numerical index of a tract. The ring indices are the ring number and the tract number within the ring. The ring number is -1 for the south polar cap and increases to the north. The north polar cap has ring number = numRings. The tract number is zero for either of the polar caps.

Return a SHA1 hash that uniquely identifies this SkyMap instance. Returns ------- sha1 : `bytes` A 20-byte hash that uniquely identifies this SkyMap instance. Notes ----- Subclasses should almost always override ``updateSha1`` instead of this function to add subclass-specific state to the hash.
