Get the polygon enclosed by two isochrones.

Parameters:

  • models (Table) – All stellar evolution models in a single astropy table, as retrieved by stam.models.read_parsec.

  • age1 (float, optional) – Stellar track age of the first track, in Gyr.

  • mh1 (float) – Stellar track metallicity ([M/H]) of the first track, in dex.

  • age2 (float, optional) – Stellar track age of the second track, in Gyr.

  • mh2 (float) – Stellar track metallicity ([M/H]) of the second track, in dex.

  • age_res (float, optional) – Age resolution, in Gyr (default: 0.001 Gyr). If negative - treat as fractional.

  • log_age_res (float, optional) – log(age/yr) resolution, in dex, if using log_age as one of the params (default: 0.05 dex).

  • mh_res (float, optional) – Metallicity resolution, in dex (default: 0.05 dex).

  • mass_res (float, optional) – Mass resolution, in Msun (default: 0.007 Msun).

  • mass_max (float, optional) – Maximum mass to consider, in Msun (if no fixed mass was chosen; default: 1.2 Msun).

  • stage1 (int, optional) – Stellar evolution stage label of the first track (0 = pre-MS, 1 = MS, etc.; default: 1).

  • stage2 (int, optional) – Stellar evolution stage label of the second track (0 = pre-MS, 1 = MS, etc.; default: 1).

  • bp_rp_min (float, optional) – Minimal Gaia Gbp-Grp color to consider (default: -np.inf).

  • bp_rp_max (float, optional) – Maximal Gaia Gbp-Grp color to consider (default: np.inf).

  • bp_rp_shift1 (float, optional) – How much to shift the Gaia Gbp-Grp color of the first track (default: 0).

  • bp_rp_shift2 (float, optional) – How much to shift the Gaia Gbp-Grp color of the second track (default: 0).

  • mg_shift1 (float, optional) – How much to shift the Gaia G-band of the first track (default: 0).

  • mg_shift2 (float, optional) – How much to shift the Gaia G-band of the second track (default: 0).

Returns:

polygon – The polygon enclosed by the two stellar evolutionary tracks.

Return type:
