Basic Usage

For simplest out-of-the-box usage after installation, make a file called star.ini that looks something like this:

Teff = 5770, 100
feh = 0.0, 0.15
logg = 4.5, 0.1
V = 10.0, 0.05

Any combination of spectroscopic or [supported] photometric properties, as well as parallax, can go as properties into this file.

Once you've made this file, type starfit at the command line. Or if you want to be organized, you can put star.ini in a folder called mystar [or whatever] and run starfit mystar from the command line. The starfit script will create an HDF5 file containing the saved StarModel, which you can load from python using StarModel.load_hdf, as well as triangle plots illustrating the fit.
