Hi,<br>
<br>
Just sending a follow-up plot illustrating what I was talking about
in yesterday's meeting. The basic details are in my presentation
from last week, and the attached plot shows a Kaon missing mass
spectrum with a carbon function of the form <i>pol(3) + Gaussian +
Gaussian </i>subtracted. This over-subtracts in a similar way to
the single Gaussian version from last week, so I add back a pol(3)
function that would describe the smaller non-carbon background.
This is all done in the range MMK = 0.9 - 1.475 GeV, hence the
discontinuity at those points. Right now, I can't describe this as
anything other than cheating, but if there were a way to
simultaneously fit the two polynomials before subtraction, it might
be possible to avoid this, or at least explain why the second
polynomial needs to be added back after fitting the first one.<br>
<br>
Cheers,<br>
