descale_bti

ChiantiPy.tools.util.descale_bti(bte, btx, f, ev1)

Apply ionization descaling of [R51] to energy and cross-section.

Parameters:

bte : array-like

Scaled energy

btx : array-like

Scaled cross-section

f : float

Scaling parameter

ev1 : float

ionization potential - units determine the output energy units

Returns:

[energy,cross] : list

Descaled energy and cross-section

Descale ionization energy and cross-section

Notes

This is the scaling used and discussed in the Dere (2007) calculation [1] of cross sections. It was derived from similar scalings provided by reference [2]
