What are the differences between White Beam and Super White Beam, if any?

The output 1D data from VSANS when White Beam or Super White Beam collimation is used is similar to the case of pinhole collimation with one VERY NOTABLE DIFFERENCE:

• The white beam and super white beam distributions are NOT symmetric, since they are not typical output from a velocity selector. This asymmetric distribution cannot be combined into the Gaussian resolution function. Therefore, the data is written with the resolution function representing ONLY the geometric contribution to the resolution. The wavelength smearing effect for these distributions is VERY SIGNIFICANT and must be correctly accounted for by a numerical integration during data analysis. See the VSANS documentation for the details of the proper handling of the white beam and super white beam wavelength distributions.
