ess.amor.resolution.wavelength_resolution(da, chopper_1_position, chopper_2_position)[source]#

Find the wavelength resolution contribution as described in Section 4.3.3 of the Amor publication (doi: 10.1016/j.nima.2016.03.007).

Parameters:

  • chopper_1_position (Chopper1Position[types.SampleRun (str)]) – Position of first chopper (the one closer to the source).

  • chopper_2_position (Chopper2Position[types.SampleRun (str)]) – Position of second chopper (the one closer to the sample).

  • pixel_position – Positions for detector pixels.

Returns:

ess.amor.types.WavelengthResolution (scipp.Variable) – The angular resolution variable, as standard deviation.
