Provides simple interface for interacting with stellar model grids.
pip install isochrones or by cloning the repository
python setup.py install.
Depends on normal scientific libraries (e.g.
as can easily be installed trouble-free via, e.g., the anaconda python distribution.
Stellar fits will want to use
pymultinest if those packages are installed (recommended); otherwise the fits will default to MCMC fitting using
For simplest out-of-the-box usage after installation, make a file called
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]
starfit mystar from the command line. The
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.
