calc_sample_position(kappa_start: float, phi_start: float, kappa_end: float, phi_end: float, sampx: float, sampy: float, phiy: float) → dict

Calculate the translation correction for inversed kappa goniostats.

For more info see Acta Cryst.(2011). A67, 219-228, Sandor Brockhauser et al., formula (3).

Parameters:

• positions (motor) –
