Radio Astronomy data analysis software

There are a growing number of software packages for reduction and analysis of data from radio astronomy facilities. They have many capabilities in common, with differences related to the instrument which provided the data, and to the user interface.

The ATNF also hosts a list of software tools.

Data Analysis Software

fitsplode fitsplode is a simple tool for extracting spectral line data that is stored in binary FITS tables. It works for Effelsberg raw data in MBFITS format and Arecibo raw data in CIMAFITS format.
MeqTrees MeqTrees is a software package for implementing Measurement Equations. This makes it uniquely suited for simulation and calibration of radioastronomical data, especially that involving new radiotelescopes and observational regimes.
Obit Obit is a group of software packages for handling radio astronomy data, especially interferometric and single dish OTF imaging.

Data Manipulation Environments

Python and friends Python is the popular object-oriented scripting language and when combined with a number additional packages, it becomes an extremely powerful data manipulation environment for astronomy. I use Python together with iPython and SciPy including NumPy and matplotlib, and I rely heavily on PyEphem and PyFITS. Other pacakages for astronomy include PySpecKit, astropy, and astLib.
IDL Interactive Data Language
GDL GNU Data Language “A free IDL (Interactive Data Language) compatible incremental compiler ”
PerlDL Perl Data Language “gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing.”
MatLab “The Language of Technical Computing”
GNU Octave GNU Octave “provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.”
MathCAD “The unique Mathcad visual format and scratchpad interface integrate standard mathematical notation, text, and graphs in a single worksheet”
Mathematica Mathematica is an “integrated system to deliver unprecedented workflow, coherence, reliability, and innovation.”
Scilab “The open source platform for numerical computation”
