astLib Description

A set of free Python tools that provides some tools for research astronomers astLib can be used for astronomical plots, some statistics, coordinate conversions, common calculations, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Doug Mink. PyWCSTools is distributed (and developed) as part of astLib. What's New in This Release: · Faster contour overlay generation code enabled by default (an optional, slower "high accuracy" mode can alternatively be selected instead). Fixed a regression introduced in 0.3.0 that stopped contour generation working over images with headers without CDi_j matrices. · Fixed bug when parsing FITS headers with extra long header cards (as can be found in e.g. headers of some Chandra images). Previously, these would cause the coordinate conversion routines to fail. · Added some extra plot objects to ImagePlot (new plot symbols, a scale bar). · Rewritten coordinate axes labelling in ImagePlot - should now be much more robust, and automatically choose sensible tick steps. If it doesn't, it can now be easily overridden. · Added clipUsingRADecCoords, resampleToTanProjection to astImages module.
