Installation

Downloading the Package

The latest version of saltfppipe is always available from its page on github. Use the green “Clone or Download” button to either clone the git repository on your local system or download the project as a .zip archive.

Building the Optional voigtfit module

saltfppipe comes with an optional python module called voigtfit, which is built from compiled Fortran code. The module is designed to fit Voigt profiles to the H-alpha line of excited hydrogen and (optionally) the [NII] line 21 Angstroms redward of H-alpha.

If you are using saltfppipe to produce H-alpha velocity fields, you’ll want to build this module.

If you are using saltfppipe only to produce data cubes, the module is unnecessary and you can skip ahead.

In the cloned respository or unzipped directory, execute the following commands:

$ cd voigtfit
$ make
$ cd ..

Note

voigtfit requires the f2py and gfortran packages to be installed

Installing the Package

To install the package, run the following command in the cloned repository or unzipped directory:

$ python setup.py install

This will install the saltfppipe package in your python packages library.

If you built the optional voigtfit module, it will be installed automatically.

Note

If your python installation is root-protected, you may need to execute the install command as sudo.
