Running the old and new algorithms/scripts produce identical results:

#!python
config['default.instrument'] = 'INTER'
LoadISISNexus(Filename='13463', OutputWorkspace='13463')
LoadISISNexus(Filename='13464', OutputWorkspace='13464')
run = LoadISISNexus(Filename='13460', OutputWorkspace='13460')

incidentAngle = 0.7

trans_ws_new = CreateTransmissionWorkspaceAuto(Params= 0.02,
                                           StartOverlap=10.0, 
                                           EndOverlap=12.0, 
                                           FirstTransmissionRun='13463', 
                                           SecondTransmissionRun='13464')



IvsQ_new, IvsLam_new, thetaOut_new= ReflectometryReductionOneAuto(InputWorkspace=run, ThetaIn=incidentAngle, FirstTransmissionRun=trans_ws_new)

from isis_reflectometry.quick import quick
IvsLam, IvsQ, thetaOut=quick(run, trans=trans_ws_new, theta=incidentAngle)


plotSpectrum([IvsQ_new, IvsQ], 0)

Doing the same thing in the reflectometry gui produces plots that are scaled differently. We need to understand what is happening here.
