# Installation¶

This code requires the following packages:

• matplotlib
• numpy v1.6 or greater
• scipy v0.13 or greater
• astropy v0.2 or greater
• lockfile
• pysynphot v0.7 or greater
• fortranformat
• cython
• requests

The bolded entries are required before installation, so make sure you get them from pip, apt-get/yum, or conda (depending on your OS and linux distribution). The setup script will attempt to install the rest if you don’t have them, but I suggest doing it yourself just to make sure nothing goes wrong. Once you have the dependencies, simply type

pip install TelFit


to install TelFit. It may take a while, as it needs to build the LBLRTM code and some of its standard input files.
