hyperspy.misc.eels.hydrogenic_gos module

class hyperspy.misc.eels.hydrogenic_gos.HydrogenicGOS(element_subshell)

Bases: hyperspy.misc.eels.base_gos.GOSBase

Computes the K and L GOS using R. Egerton’s routines.

Parameters:element_subshell (str) – For example, ‘Ti_L3’ for the GOS of the titanium L3 subshell

parametrize_GOS()

Parametrize the GOS to speed up the calculation.

get_qaxis_and_gos(ienergy, qmin, qmax)

Given the energy axis index and qmin and qmax values returns the qaxis and gos between qmin and qmax using linear interpolation to include qmin and qmax in the range.

energy_axis

array – The tabulated energy axis

qaxis

array – The tabulated qaxis

energy_onset

float – The energy onset for the given element subshell as obtained from iternal tables.

Notes

The Hydrogeninc GOS are calculated using R. Egerton’s SIGMAK3 and SIGMAL3 routines that has been translated from Matlab to Python by I. Iyengar. See http://www.tem-eels.ca/ for the original code.
