Goniometer can not work with psi value loaded from nxspe file

Reported by: Alex Buts Owned by: Andrei Savici
Priority: major Milestone: Release 2.2
Component: Mantid Keywords:

Description

goniometer expects time series property and psi is loaded as a number property.

additional enhancement, which needs discussion would be setting the goniometer into psi,0,1,0,1 position when loading nxspe file too.

Here is the test 

Load(Filename='CNCS_7860_event.nxs',OutputWorkspace='in')
ConvertUnits(InputWorkspace='in',OutputWorkspace='in',Target='DeltaE',EMode='Direct',EFixed='3')
Rebin(InputWorkspace='in',OutputWorkspace='in',Params='-3,0.05,3')
SaveNXSPE(Filename='test.nxspe',InputWorkspace='in',Efixed='3',Psi='10')
LoadNXSPE(Filename='test.nxspe',OutputWorkspace='out')
SaveNexus(Filename='test.nxs',InputWorkspace='out')

Use hdfview to inspect test.nxs. It should have a goniometer, num_axes=1, and in axis 0: name='psi', angle='10',rotationaxis='0,1,0'

Added goniometer on LoadNXSPE. Refs #5250

Allow run object to set goniometer on PropertyWithValue, not only TimeSeriesProperty

Shouldn't the units be degree rather than deg ?

Also, there isn't a nexus class called NXmotor - that is what NXpositioner is for.

But these are minor side issues! :-)
