Yes, or just call the AIDA objects directly. This sort of interface
stuff will have to change when we replace AIDA.

The bin width factors should be canceled out in the division, but it's
possible that LWH's implementation of the histogram division gets this
wrong and includes the width factor when creating the DataPointSet.
That's worth checking (and fixing if it's the case).
