How to download isochrones from CMD 3.4

last tested: 2021-03-31

# import CMD
from berliner.parsec import CMD
# initialize it
c = CMD()

# Example 1: download one isochrone
    logage=9.0,     # log age
    z=0.0152,       # if [M/H] is not set, z is used
    mh=None,        # [M/H]
    photsys_file='2mass_spitzer', # photometric system

# Example 2: download a grid of isochrones
# define your grid of logAge and [M/H] as tuple(lower, upper, step)
grid_logage = (6, 10.2, 0.1)
grid_mh = (-2.6, 0.5, 0.1)
# download isochrones in parallel
isoc_lgage, isoc_mhini, isoc_list_2mass_wise = c.get_isochrone_grid_mh(
    grid_logage=grid_logage, grid_mh=grid_mh, photsys_file="2mass_spitzer_wise",
    n_jobs=50, verbose=10)
