    7070Third, repeat the refinement using the Peak Fitting/LSQ !PeakFit menu item.
    7171 
    72 Fourth, select peak widths for refinement. This can be done by refining sigma (Gaussian width) and/or gamma (Lorentzian width) for individual peaks, but here we constrain the peaks to follow an instrumental broadening equation. Select the Instrumental Parameters
    73 this opens a window for peak profile terms
     72Fourth, select peak widths for refinement. This can be done by refining sigma (Gaussian width) and/or gamma (Lorentzian width) for individual peaks, but here we constrain the peaks to follow an instrumental broadening equation. Select the Instrumental Parameters item in the data tree.

    7575Select the refine flag checkbox for Gaussian U, V, W, Lorentzian X, Y and the asymmetry parameter SH/L.

    77 Fifth, repeat the refinement using the Peak Fitting/LSQ !PeakFit menu item. At this point a good fit should be seen by zooming in on individual peaks. (For example see
    78 [https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/wiki/DemoAutoIndex/d3w7.png this]).
     77Fifth, repeat the refinement. First click on the Peak List item in the data tree and then refine using the Peak Fitting/LSQ !PeakFit menu item. At this point a good fit should be seen by zooming in on individual peaks. (For example see
     78[https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/wiki/DemoAutoIndex/d3w7.png this]). The Rwp is ~6%.
