.. module:: isochrones
This page details the methods and classes provided by the
isochrones package. The :class:`ModelGrid` object handles
the book-keeping aspects of loading a given grid into a pandas.DataFrame
object. However, :class:`ModelGrid` works behind the scenes; you should
usually only work directly through the :class:`Isochrone` object, which handles the grid interpolation. Finally, the :class:`StarModel` object is used to fit the stellar models constrained by observed data.
.. autoclass:: isochrones.grid.ModelGrid
:members:
Any usage of isochrones involves instantiating an
:class:`Isochrone`, usually through a specific subclass such as
:class:`mist.MIST_Isochrone`.
.. autoclass:: isochrones.Isochrone :members:
.. autoclass:: isochrones.FastIsochrone :members:
Stellar model grids from the MESA Isochrones and Stellar Tracks. These grids cover a larger range in mass, age, and [Fe/H], compared to the Dartmouth grids, and are thus preferred. Because this is a larger grid, interpolation here is implemented via the :class:`FastIsochrone` implementation, rather than the standard Delaunay triangulation-based :class:`Isochrone` implementation.
.. autoclass:: isochrones.mist.MIST_Isochrone :members:
Stellar model grids from the Dartmouth Stellar Evolution Database. Because these grids contain fewer points, both interpolation options are available: :class:`Dartmouth_Isochrone` and :class:`Dartmouth_FastIsochrone`.
.. autoclass:: isochrones.dartmouth.Dartmouth_Isochrone :members:
.. autoclass:: isochrones.dartmouth.Dartmouth_FastIsochrones :members:
Estimating a star's physical properties based on a set of observed properties involves instantiating a :class:`StarModel`.
