Description
DiffractionFocussing should support input workspaces in Q (read: momentum transfer) as well as d-spacing since they have some requirements on the data being commensurate.
This will help with processing data for PDF reduction.

The following scripts shows a fairly significant difference between the Workspace2D and event versions of the algorithm:
# 2D version LoadEventNexus(Filename="/home/8oz/data/PG3_1370_event.nxs",OutputWorkspace="pg3",CompressTolerance="0.050000000000000003") ConvertUnits(InputWorkspace="pg3",OutputWorkspace="pg3",Target="MomentumTransfer") Rebin(InputWorkspace="pg3",OutputWorkspace="pg3",Params="0,1,40") CreateGroupingWorkspace(InstrumentName="PG3",GroupNames="bank124,bank144,bank164,bank184",OutputWorkspace="pg3_group") ConvertToMatrixWorkspace(InputWorkspace="pg3",OutputWorkspace="pg32d") DiffractionFocussing(InputWorkspace="pg32d",OutputWorkspace="pg3_foc_2d",GroupingWorkspace="pg3_group") # Event version CreateGroupingWorkspace(InstrumentName="PG3",GroupNames="bank124,bank144,bank164,bank184",OutputWorkspace="pg3_group") DiffractionFocussing(InputWorkspace="pg3",OutputWorkspace="pg3_foc",GroupingWorkspace="pg3_group") Minus("pg3_foc", "pg3_foc_2d", "pg3_diff")
If you compare pg3_foc and pg3_foc_2d on a plot, they look pretty different. I'm not sure if this is specific to Q; or if it has something to do with Martyn's "fixes" to spectrum numbers. Maybe this should reopen a new ticket?
