plots which include the correlations are here:

the spreadsheet used to produce the plots is

Please note that the correlations are not yet taken into account for
intpur>0.5, as I could not find the appropriate logfile. The effect of
the correlations is in any case small. Since the S and P are
ANTIcorrelated (as expected), the error on S/P increase.
Here are the double S/P ratios (MC/data) for different intpur cuts, as
resulting from a simple p0 fit. Chisquares are also shown.
intpur cut S/P chisquare/nDOF
0.20 1.33 +/- 0.15 3.5/9
0.30 1.41 +/- 0.16 2.9/9
0.40 1.19 +/- 0.17 8.7/9
0.50 1.25 +/- 0.17 8.4/9 (no correlations yet)
I would say that data and MC depleted samples agree better and their
ratio is weakly dependent on mX at higher integrated purity cuts.
Ciao, Concezio.
