Get the polygon enclosed by one side of an evolutionary track.

Parameters:

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

  • vals (array_like (of length 2)) – Values of the fixed parameters (units: [mass] = Msun, [age] = Gyr, [mh] = dex).

  • params (tuple (of length 2), optional) – Fixed parameters names (default: (“age”, “mh”)).

  • side (str, optional (default: "blue")) – Which side of the track to include (“blue”/”red”).

  • 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).

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

  • stage_min (int, optional) – Minimum stellar evolution stage label to consider (if no fixed stage was chosen; default: 0).

  • stage_max (int, optional) – Maximum stellar evolution stage label to consider (if no fixed stage was chosen; default: np.inf).

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

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

  • is_extrapolate (bool, optional) – Whether to extrapolate the massive part of the isochrone (default: True).

  • color_filter1 (str, optional) – Bluer band to use for the color calculation (default: G_BPmag).

  • color_filter2 (str, optional) – Redder band to use for the color calculation (default: G_RPmag).

  • mag_filter (str, optional) – Which band to use for the magnitude axis (default: Gmag).

Returns:

polygon – The polygon enclosed by one side of an evolutionary track.
