Installation¶
The installation of speedyfit requires two steps, installing the python package, and downloading the required atmosphere models. The speedyfit package can be installed with pip from the pypi repository as follows:
pip install speedyfit
If you want install the current development version directly from github you can also use pip:
pip install git+https://github.com/vosjo/speedyfit.git#egg=speedyfit
The atmosphere models that speedyfit uses to fit the SEDs can be downloaded from:
Download them and unpack them in a directory of your choice. The last step is to store the path to the atmosphere models in an environment variable so that Speedyfit will know where to get them. In a bash shell this is done as follows:
export SPEEDYFIT_MODELS="<path to extracted atmosphere models>"
Where the path could be something like: ‘/home/user/speedyfit/modelgrids/’. To not always have to type this in the terminal when running Speedyfit, you can add it to your ‘.bashrc’ file.
To check that speedyfit can find all models run:
speedyfit checkgrids
Which if everything went well should give you the following output:
Checking which atmosphere models are available...
Checking for models in <path to extracted atmosphere models>
kurucz2
raw: available
integrated: available
munari

integrated: available
tmap

blackbody

integrated: available
If you get an error like:
SPEEDYFIT_MODELS environmental variable not set. CAN NOT find models!
Please point the SPEEDYFIT_MODELS variable to the directory where you stored models.
On bash use:
export SPEEDYFIT_MODELS='<path to extracted atmosphere models>'
Check that your “SPEEDYFIT_MODELS” variable is correctly set up. If you get “NOT FOUND” instead of “available” for any of the models, check that the “SPEEDYFIT_MODELS” variable points to the correct directory, and that the directory contains the extracted atmosphere models.
To uninstall Speedyfit, run:
pip uninstall speedyfit
