ess.nmx.scaling.estimate_scale_factor_per_hkl_asu_from_reference(reference_intensities)[source]#

Calculate the estimated scale factor per hkl_asu.

The estimated scale factor is calculated as the average of the inverse of the non-empty reference intensities.

It is part of the calculation of estimated scaled intensities for fitting the scaling model.

E s t i m a t e d S c a l e F a c t o r_{(h k l)} = \frac{\sum_{i = 1}^{N_{(h k l)}} \frac{1}{I_{i}}}{N_{(h k l)}} = a v e r a g e (\frac{1}{I_{(h k l)}})

Estimated scale factor is calculated per hkl_asu. This is part of the calculation of roughly-scaled-intensities for fitting the scaling model. The whole procedure is described in average_roughly_scaled_intensities().

Parameters:

reference_intensities (scaling.ReferenceIntensities (scipp.DataArray)) – The reference intensities selected by wavelength.

Returns:

scaling.EstimatedScaleFactor (scipp.DataArray) – The estimated scale factor per hkl_asu. The result should have a dimension of hkl_asu.

It does not have a dimension of wavelength since it is calculated from the reference intensities, which is selected by one wavelength.
