Hi,
in order to make sure we are tuned, I would like to summarize the
discussion of today. Please react if the summary is not faithful.

-1) technicalities
the duplicate killing is available only for generic MC, Urs will try and
get it going for the rest. This is on the critical path for producing the
very final root files.
Also Urs will tag the version of anaRecoil used for this "final"
production as soon as he gets the commits from Ric and Daniele and
implements his own last changes.

0) blinding
it has been implemented: daniele will commit asap


1) new cut selection and Breco systematics
The fit on generic Mc with the GTLV+AS selection is a couple of sigmas
away from the generated value (and ~3 uncorrelated sigmas from the fit
with the CT+AS selection). Statistics is unfortunately quite limited.
This effect is also correlated to the studies from Luigi which show that
varying the purity of the data for fixed purity of the model, there is a
quite significant effect at an integrated purity of about 79% (roughly the
one corresponding to the cocktail).

We assume that we will able to insert this effect into the systematics and
go ahead and use the selection which has great advantages: better pHad and
better Qtot agreement between data and MC.

Nonetheless to understand the effect it was suggested that:
	- we perform the stability test for several purities on data
(blind) so that we double the statistics the test is done upon.
	- we perform the MC test using only SP3 and only SP4 to avoid
problems with the compositions of the two MC releases.
	- redo the studies of luigi on CT+AS to see if this was not an
issue before changing the selection
	- check the impact of reweighting the model in order to  reproduce
the distribution of events in the modes of the data. If this fixes the MC
the same algorithm would yield the systematics on data


2)  BF systematics
Ric and Daniele will try and reach Alessio to get the material to finalize
the study

3) plots for BAD:
Urs, Daniele and luigi will start feeding me with plots in order to start
arranging the BAD properly

4) mes systematics
fit will be done with gaussian and crystal ball separately and compared

5) cut variation
Once blinding is available Urs will do the M^2 and Mx cut variation and
stability check.

6) Mx cut decision

the cut on Mx will be decided optimizing the sum of the statistical error
(estimated on MC), the D and Breco systematics and the theoretical error


that's all what I have marked up
	ciao
