Change h for hbar

Reported by: Jose Borreguero Owned by: Jose Borreguero
Priority: minor Milestone: Release 3.1
Component: Indirect Inelastic Keywords:
Cc: Blocked By:
Blocking: Tester: Andrei Savici

Description (last modified by Jose Borreguero) (diff)

The correct coefficient transforming from energy to time involves hbar, not h. See updated page http://www.mantidproject.org/DiffRotDiscreteCircle

==============================================================

TESTER:

Download attached files to /tmp. In Mantidplot.Script_Window, load test.py and execute. A fit of the data should yield the followings parameters:

Intensity = 0.745, Radius = 0.876(Angstroms), Decay = 121.5(pico-seconds)

You can plot workspace data_Workspace to visually inspect the fit

You can also use the MantidPlot's fit wizard to perform the fit. Here's the starting fit-string guess that you load to the wizard via Setup->Manage_Setup->Load_From_String:

(composite=Convolution,FixResolution=true,NumDeriv=true;name=TabulatedFunction,FileName="",Workspace=resolution,Scaling=1;(name=DiffRotDiscreteCircle,N=3,NumDeriv=true,Q=1.9,Intensity=1,Radius=1,Decay=10));name=LinearBackground,A0=0.001,A1=0.0001 ==============================================================
