toast_tile_for_point(depth, lat, lon)¶
Identify the TOAST tile at a given depth that contains the given point.
- depthnon-negative integer
The TOAST tile pyramid depth to drill down to. For any given depth, there exists a tile containing the input point. As the depth gets larger, the precision of the location gets more precise.
The latitude (declination) of the point, in radians.
The longitude (RA) of the point, in radians. This value must have already been normalied to lie within the range [0, 2pi] (inclusive on both ends.)
Tileat the given depth that best contains the specified
