ess.sans.types.ProcessedWavelengthBands = ess.sans.types.ProcessedWavelengthBands

Processed wavelength bands, as a two-dimensional variable, with the first dimension being the band index and the second dimension being the wavelength. For each band, there must be two wavelength values defining the start and end wavelength of the band.

Band edges coincide exactly with values of WavelengthBins. Reducing over a band relies on this, so that event data, dense data with a bin-edge wavelength coord and dense data with a midpoint wavelength coord all select the same wavelength range. Construct this via ess.sans.normalization.process_wavelength_bands(), which establishes the alignment; hand-built bands silently bias I(Q) per band.
