In addition to the astronomy related tools (listed below from the code repository), this package includes (but is not limited to) utilities covering XML/JSON io, numpy record & structured arrays, and an IDL-like histogram statistics tool.Astronomy related tools
- wcsutil: Tools for working with the astronomical World Coordinate System format.
- cosmology: Tools for cosmological calculations. This is currently focused on distance measures.
- coords: Tools for working with astronomical coordinates and coordinate transformations. Used to be called astro_util. There is still an alias for that name available.
- htm: This is a Class to deal with the Hierarchical Triangular Mesh, which is a method for breaking the unit sphere into a tree structure where each node in the tree is represented by a spherical triangle. A primary advantage of the HTM over other schemes is that it deals perfectly well with the poles. This class contains code for matching ra/dec lists, measuring two-point correlation functions (using the bincount method), and finding node information for ra/dec points.
