scale_bti
(evin, crossin, f, ev1)[source] [edit on github]¶ Apply ionization scaling of [R89],[R90]_ 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

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]
