ess.estia.resolution.wavelength_resolution# ess.estia.resolution.wavelength_resolution(source_pulse_length, wavelength, Ltotal)[source]# Find the wavelength resolution contribution of the ESTIA instrument. Parameters: source_pulse_length (Variable) – The length of the ESS source pulse. wavelength (Variable) – The wavelength of the neutron. Ltotal (Variable) – The distance from source to detector. Returns: The wavelength resolution, ratio of the standard deviation of wavelength and the wavelength.
