Provides simple interface for interacting with stellar model grids. The guts of this code is a 3-d linear interpolation in mass, age, Fe/H space. That is, the model predicts the various properties as functions of these inputs.
Basic usage:
>>> from isochrones.dartmouth import Dartmouth_Isochrone >>> dar = Dartmouth_Isochrone() >>> dar.radius(1.0,9.6,0.0) #mass [solar], log(age), Fe/H 0.9886235
or, more generally (results returned in pandas DataFrame object):
>>> dar(1.0,9.6,0.0)

Note that the first time a stellar model module is loaded, it will download the necessary data (~few hundred MB) and save it to a folder in your home directory called ~/.isochrones.
