ess.powder.conversion.to_dspacing_with_calibration(data, calibration)[source]#

Transform coordinates to d-spacing from calibration parameters.

Computes d-spacing from time-of-flight stored in data.

Attention

data may have a wavelength coordinate and dimension, but those are discarded. Only the stored time-of-flight is used, that is, any modifications to the wavelength coordinate after it was computed from time-of-flight are lost.

Raises:

KeyError – If data does not contain a ‘tof’ coordinate.

Parameters:

data (DataArray) – Input data in tof or wavelength dimension. Must have a tof coordinate.
calibration (Dataset) – Calibration data.

Returns:

DataArray – A DataArray with the same data as the input and a ‘dspacing’ coordinate.
