Performs azimuthal averaging for a 2D SANS data set by going through
each detector pixel, determining its Q-value, and adding its amplitude
to the appropriate Q bin. For greater precision, each detector
pixel can be sub-divided in sub-pixels by setting the
NPixelDivision
parameters. Each pixel has a weight of 1 by default, but the weight of
each pixel can be set to by setting the
ErrorWeighting
parameter to True.
See the Rebin documentation for details about choosing the OutputBinning
parameter.
See SANSReduction documentation for calculation details.
This algorithm is not intended to be run individually, rather as a part of the SANSReduction.
