shone.opacity.download_atom(atom, charge, line_list='first-found', temperature_range=None, pressure_range=None, version=None)[source]#

Download atomic opacity data from DACE [1] [2].

These opacities were computed with HELIOS-K [3] [4] [5].

Warning

This generates very large files. Only run this method if you have a few GB available per atom.

Parameters:

atom (str) – For example, “Na” for sodium.
charge (int) – For example, 0 for neutral.
line_list (str, default is 'first-found', optional) – For example, “Kurucz”. By default, the first available line list for this atom/charge is chosen.
temperature_range (tuple, optional) – Tuple of integers specifying the min and max temperature requested. Defaults to the full range of available temperatures.
pressure_range (tuple, optional) – Tuple of floats specifying the log base 10 of the min and max pressure [bar] requested. Defaults to the full range of available pressures.
version (float, optional) – Version number of the line list in DACE. Defaults to the latest version.
