Astropy is a package intended to contain core functionality and some common tools needed for performing astronomy and astrophysics research with Python. It also provides an index for other astronomy packages and tools for managing them. The Astropy Project is a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python astronomy packages.
v0.3 [Dec 17, 2013]
Astropy 0.3 is a major release that adds significant new functionality since the 0.2.x series of releases. This release sees the addition of the Modeling sub-package, which provides an initial framework for fitting models to data, and the Virtual Observatory sub-package, which implements cone searches. In addition, there have been many improvements to the existing sub-packages, such as a much faster implementation of quantities for Numpy arrays in the Units and Quantities sub-package, a better integration of units and quantities in other sub-packages (such as the Cosmology sub-package), new Table functionality related to joining and aggregation, support for arrays in the Coordinates sub-package, and a re-structuring of the Convolution code to provide many build-in parameterized kernels. We describe the new sub-packages and the main improvements below.
