astLib is a set of Python modules that provides some tools for research astronomers. It can be used for astronomical plots, some statistics, common calculations, coordinate conversions, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Jessica Mink. PyWCSTools is distributed (and developed) as part of astLib.

Version 0.8.0 released

Version 0.8.0 of astLib has been released.

This release is a minor update that fixes some bugs and avoids the use of features that are deprecated in recent versions of pyfits and matplotlib. For details, please refer to the change log and updated API documentation.

Version 0.7.0 released

Version 0.7.0 of astLib has been released.

This release includes support for python 3 (tested on version 3.2.3), some bug fixes, and a couple of new routines here and there. For details, please refer to the change log and updated API documentation.

Version 0.6.1 released

Version 0.6.1 of astLib has been released.

This release fixes the bug where importing a single astLib module also triggered the undesired import of the other modules and their dependencies. So now importing only the astWCS module will not trigger importing matplotlib, for example. Otherwise, this version is identical to 0.6.0.

Version 0.6.0 released

Version 0.6.0 of astLib has been released.

This release adds support for WCSs with polynomial distortion coefficients, plus a few bug fixes. For details, please refer to the change log and updated API documentation.

Version 0.5.0 released

Version 0.5.0 of astLib has been released.

This release is a fairly minor update. For details, please refer to the change log and updated API documentation.

Version 0.4.0 released

Version 0.4.0 of astLib has been released.

This release adds new code for fitting Spectral Energy Distributions (SEDs) using stellar population models in the astSED module, plus several other new features. A major bug that previously prevented the astPlots.ImagePlot class from working under python 2.6 is also fixed in this release.

For further details, refer to the release notes, change log and updated API documentation.

Version 0.3.2 Released

Version 0.3.2 of astLib has been released.

This release provides a number of bug fixes (including a long overdue fix to handle image headers with HIERARCH keywords), plus some minor enhancements.

For further details, refer to the release notes, change log and updated API documentation.

Version 0.3.1 Released

This release fixes several bugs and adds a couple of new features.

For further details, refer to the release notes, change log and updated API documentation.

Version 0.3.0 Released

astLib version 0.3.0 has been released.

The major additions in this release are a new module for calculating colours and magnitudes from spectral energy distributions (astSED), and the new ImagePlot class. Several new functions, bug fixes, and enhancements have also been added across the existing modules.

For further details, refer to the release notes, change log and updated API documentation.

Version 0.2.0 Released

Version 0.2.0 of astLib has been released.

This release adds a number of bug fixes and new features including:

  • Improved install script - now builds on x86-64.
  • New routines for producing image plots with WCS coordinate axes in the astPlots module - two new example scripts are included demonstrating their use.
  • Image clipping and rotation routines in the astImages module now return correctly updated WCS objects.
  • Other minor bug fixes and usability improvements.
