Yes, I will let it work by Friday.

once it works it's only a matter of job submission with different cuts.
I need to know: do we want to produce these numbers for the all 
reweighting schema (that is: use Wolfgang's latest tag and also the 
numbers on D** computed by Chukwudi)? In this case, before fitting the 
S/P ratio with a gaussian I have to re-dump weighted dataset and 
recompute the S/P ratio itself.
