Provides simple interface for interacting with stellar model grids.
Install with pip install isochrones or by cloning the repository
and running python setup.py install.
Depends on normal scientific libraries (e.g. numpy, pandas, etc.),
as can easily be installed trouble-free via, e.g., the anaconda python distribution.
For usage details, read the documentation or check out the demo notebook.
Stellar fits will want to use MultiNest/pymultinest if those packages are installed (recommended); otherwise the fits will default to MCMC fitting using emcee.
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.
