Table of Contents
This algorithm performs an integration over an energy range, with the option to subtract a background over a second range, then transposes the result into a single-spectrum workspace with units in Q and Q^2.

This algorithm Integrates over the range specified, converts the spectrum axis into units of Q and Q^{2} and transposes the result workspaces.
There are two output workspaces.
