ConfigClass = EquatSkyMapConfig | |
Equatorial sky map pixelization, e.g. for SDSS stripe 82 image data. EquatSkyMap represents an equatorial band of sky divided along declination into overlapping tracts.

config = None |

) |
Construct a EquatSkyMap @param[in] config: an instance of self.ConfigClass; if None the default config is used

Find closest tract and patches that overlap coordinates @param[in] coordList: list of ICRS sky coordinates (lsst.afw.geom.SpherePoint) @return 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.

Find the tract whose center is nearest the specified coord. @param[in] coord: ICRS sky coordinate (lsst.afw.geom.SpherePoint) @return TractInfo of tract whose center is nearest the specified coord @warning: - if tracts do not cover the whole sky then the returned tract may not include the coord @note - This routine will be more efficient if coord is ICRS. - If coord is equidistant between multiple sky tract centers then one is arbitrarily chosen. - The default implementation is not very efficient; subclasses may wish to override.

Find tracts and patches that overlap a region @param[in] coordList: list of ICRS sky coordinates (lsst.afw.geom.SpherePoint) @return 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. @warning this uses a naive algorithm that may find some tracts and patches that do not overlap the region (especially if the region is not a rectangle aligned along patch x,y).

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