scale_bti

ChiantiPy.tools.util.scale_bti(evin, crossin, f, ev1)[source] [edit on github]

Apply ionization scaling of [R56],[R57]_ to energy and cross-section.

Parameters:

evin : float

Energy - same units as ev1

crossin : array-like

Cross-section

f : float - the scale factor

ev1 : float

the ionization potential units - the same as evin

Returns:

[bte,btx] : list

Scaled 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 derived in reference [2]
