ChiantiPy.tools.io.vernerRead()[source] [edit on github]

Reads the photoionization cross-section data from [R49].

Returns:

{‘pqn’,’l’,’eth’,’e0’,’sig0’,’ya’,’p’, yw’} : dict

pqn is the principal quantum number, l is the subshell orbital quantum number, eth (in eV) is the subshell ionization threshold energy; sig0, ya, p, and yw are all fit parameters used in calculating the total photoionization cross-section.
