That's what I suspected, and with this guidance I found it quickly. The
module is added and seems to set the dv correctly from the calibration db.
(SetUseDriftVelocity isn't called, but it's kTRUE by default...)

This still leaves me wondering why I see such nice MRS results if the dv
is off by three orders of magnitude...

Thanks, Peter.
