v3 v4 70 70 Third, repeat the refinement using the Peak Fitting/LSQ !PeakFit menu item. 71 71 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 terms72 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 item in the data tree. 73 This opens a window for peak profile terms 74 74 ([https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/wiki/DemoAutoIndex/d3w6.png view]). 75 75 Select the refine flag checkbox for Gaussian U, V, W, Lorentzian X, Y and the asymmetry parameter SH/L. 76 76 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 see78 [https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/wiki/DemoAutoIndex/d3w7.png this]). 77 Fifth, 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%.
