TimeOfFlightInstrument.calc_resolution(hkle)

For a scattering vector (H,K,L) and energy transfers W, given experimental conditions specified in the object, calculates the resolution matrix RMS and Resolution prefactor R0 in a coordinate system defined by the crystallographic axes of the sample, (h, k, l, w) in reciprocal lattice units (rlu).

Parameters:

hkle : list

Array of the scattering vector and energy transfer at which the calculation should be performed
