Pei,
The following page will help:

I think what you are seeing is just effects of removing data that
contributes to the mu(E) spectrum.
As for why the feature (low-R junk) increases as Rbkg is adjusted from 1.0
to 1.21 but disappears at 1.22, I'm not sure but my guess is that this is
an artifact of removing some of the data that contributes to the feature,
and by 1.22 you have removed enough that the feature disappears (hopefully
someone will correct me if I'm wrong). I would be weary of using an Rbkg
of 1.22 though (as I think you see why in the plots - Question 3).
Cheers,
Richard
