Detailed Description

Part of data reduction for SANS.

Transforms a 2D detector array into I(Q) by assigning each 2D pixel to a Q bin. The contribution of each pixel is weighted by either 1 or a function of the error on the signal in that pixel.

The weighting of the pixel by the error follows the HFIR/SANS reduction code implemented in IGOR by Ken Littrell, ORNL.

Choosing to weight each pixel by 1 gives I(q) where each bin is the average of all pixels contributing to that bin.

Each pixel is sub-divided in NPixelDivision*NPixelDivision sub-pixels when averaging.

Required Properties:

InputWorkspace - The (partly) corrected data in units of wavelength.
OutputWorkspace - The workspace in which to store the result histogram.
OutputBinning - The bin parameters to use for the final result.
NPixelDivision - The number of pixel sub-divisions in each direction used for calculation.
PixelSizeX - The pixel size, in meter, in the X direction.
PixelSizeY - The pixel size, in meter, in the Y direction.
ErrorWeighting - Whether to weight pixel contribution by their error (default: false).
