First public release (0.1)

astLib is a set of Python modules that provides tools for research astronomers. It can be used for simple plots, statistics, common calculations, coordinate conversions, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Doug Mink (http://tdc-www.harvard.edu/software/wcstools). PyWCSTools is distributed (and developed) as part of astLib. ... read more
