Dear colleagues,

We are very happy to announce the second major public release (v0.3)
of the Astropy package, a core Python package for Astronomy:


Astropy is a community-driven package intended to contain much of the
core functionality and common tools needed for performing astronomy
and astrophysics with Python.

New and improved functionality in this release includes:

* A new modeling package which provides a framework for fitting models to data
* Quantity has been re-implemented as a numpy array subclass,
enhancing performance and usability
* Unit conversion and Quantities are better integrated with other
parts of Astropy, simplifying many APIs and user code.
* New Table functionality for joining and aggregating tables
* Support for arrays of celestial coordinates
* A new virtual observatory cone search package
* A dedicated convolution sub-package with many predefined kernels

A full list of improvements, including examples, is provided at:


Instructions for installing Astropy are provided at the
http://www.astropy.org website, and extensive documentation can be

at the end of paperst:

"This research made use of Astropy, a community-developed core Python
package for Astronomy (Astropy Collaboration, 2013)."
