Information for a tract specified explicitly. A tract is placed at the explicitly defined coordinates, with the nominated radius. The tracts are square (i.e., the radius is really a half-size).

Does this tract contain the coordinate?
Definition at line 396 of file tractInfo.py.

Find the patch containing the specified coord. Parameters ---------- coord : `lsst.geom.SpherePoint` ICRS sky coordinate to search for. Returns ------- result : `lsst.skymap.PatchInfo` PatchInfo of patch whose inner bbox contains the specified coord Raises ------ LookupError If coord is not in tract or we cannot determine the pixel coordinate (which likely means the coord is off the tract).
Definition at line 186 of file tractInfo.py.
|
inherited |
Find patches containing the specified list of coords. Parameters ---------- coordList : `list` of `lsst.geom.SpherePoint` ICRS sky coordinates to search for. Returns ------- result : `list` of `lsst.skymap.PatchInfo` List of PatchInfo for patches that contain, or may contain, the specified region. The list will be empty if there is no overlap. Notes ----- **Warning:** - This may give incorrect answers on regions that are larger than a tract. - This uses a naive algorithm that may find some patches that do not overlap the region (especially if the region is not a rectangle aligned along patch x,y).

Convert sequential index into patch index (x,y) pair. Parameters ---------- sequentialIndex : `int` Returns ------- x, y : `lsst.skymap.Index2D`
Definition at line 173 of file tractInfo.py.
|
inherited |
Return information for the specified patch. Parameters ---------- index : `typing.NamedTuple` ['x': `int`, 'y': `int`] Index of patch, as a pair of ints; or a sequential index as returned by getSequentialPatchIndex; negative values are not supported. Returns ------- result : `lsst.skymap.PatchInfo` The patch info for that index. Raises ------ IndexError If index is out of range.
