ess.sans.i_of_q.convert_to_q_and_merge_spectra¶
- ess.sans.i_of_q.convert_to_q_and_merge_spectra(data, graph, wavelength_bands, q_bins, gravity)¶
Convert the data to momentum vector Q. This accepts both dense and event data. The final step merges all spectra:
In the case of event data, events in all bins are concatenated
In the case of dense data, counts in all spectra are summed
- Parameters
data (
DataArray) – A DataArray containing the data that is to be converted to Q.graph (
dict) – The coordinate conversion graph used to perform the conversion to Q.wavelength_bands (
Variable) – Defines bands in wavelength that can be used to separate different wavelength ranges that contribute to different regions in Q space. Note that this needs to be defined, so if all wavelengths should be used, this should simply be a start and end edges that encompass the entire wavelength range.q_bins (
Variable) – The binning in Q to be used.gravity (
bool) – If True, include the effects of gravity when computing the scattering angle.
