⚡️ Build and Install RADEX easily


Radex is a computer program to calculate the strengths of atomic and molecular lines from interstellar clouds which are assumed to be homogeneous. - RADEX website

This project will make it easier to use RADEX for radio astronomers. The Makefile or the Homebrew formula will automatically build and install three different RADEX binaries:

Binary Descripion
radex-uni RADEX built with option 1 (uniform sphere)
radex-lvg RADEX built with option 2 (expanding sphere)
radex-slab RADEX built with option 3 (plane parallel slab)

As a major difference from the normal RADEX installation, the path of data directory (the parameter of radat) is not set by default. This allows users to specify the relative or full path of a data file when you run RADEX. Please note that the tilde expansion (e.g., ~/) cannot be used.



The easiest way is to use Homebrew:

$ brew tap astropenguin/formulae
$ brew install radex

As a dependency, gcc (for using gfortran) will be also installed. The built binaries are installed in Homebrew's bin directory in the same manner as other Homebrew's formulae.

Clone this repository

Another way is to build and install by yourself:

$ git clone
$ cd radex-install
$ make install

Users must prepare gfortran before the installation. The built binaries are installed in ~/.local/bin and these paths are symlinked to /usr/local/bin. In this way of the installation, you can customize several parameters like:

$ make install DATADIR=/Users/astropenguin/radex/data/

The list of all customizable parameters are listed below.

Parameter Default Description
DATADIR not defined (see above) path of directory for RADEX data files (.dat)
LOGFILE ./radex.log path of log file
MINITER 10 the number of minimum iterations in RADEX
MAXITER 9999 the number of maximum iterations in RADEX
You can’t perform that action at this time.
