Have you looked at this: https://subversion.xray.aps.anl.gov/pyGSAS/Tutorials/BkgFit/FitBkgTut.htm, but why is your zero-background plate giving you peaks? It should be off-cut so that there is no Bragg diffraction.

I am unable to figure out how to subtract/ignore the peaks associated with the zero-background holder. Any advice is appreciated, thanks in advance.
