README

**astLib** provides some tools for research astronomers who use Python.

* **Documentation:** https://astlib.readthedocs.io

* **License:** `LGPL `_

* **Authors:** Matt Hilton & Steven Boada

* **Installation:** ``pip install astLib``

* **Support:** Please use the `GitHub issues page `_,

  and/or contact `Matt Hilton `_.

**astLib** is divided into several modules:

* astCalc   (general calculations, e.g. luminosity distance etc.)

* astCoords (coordinate conversions etc.)

* astImages (clip sections from .fits etc.) 

* astPlots  (provides a flexible image plot class, e.g. plot image with catalogue objects overlaid)

* astSED    (calculate colours, magnitudes from stellar population models or spectral templates, fit photometric observations using stellar population models etc.)

* astStats  (statistics, e.g. biweight location/scale estimators etc.)

* astWCS    (routines for using FITS World Coordinate System information)

The astWCS module is a higher level interface to PyWCSTools, a simple SWIG (http://www.swig.org) wrapping 

of some of the routines from WCSTools by Jessica Mink (http://tdc-www.harvard.edu/software/wcstools/). It is 

used by some routines in astCoords, astImages and astPlots.

The goal of **astLib** was to provide features useful to astronomers that are not included in the scipy

(http://scipy.org), numpy (http://numpy.scipy.org) or matplotlib (http://matplotlib.sourceforge.net) modules 

on which astLib depends. For a far more extensive set of Python astronomy modules, see astropy 

(http://www.astropy.org/).

Some scripts using **astLib** can be found in the examples/ folder provided with the source code distribution.
