Hi all,

 here the results on the first available part of the new production

 DATA
 ----

 Stat 8.1 fb-1 (I updated the web pages)

 http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-2.html DstarX
 http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-4.html DcX
 http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-3.html Dstar0X
 http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-5.html D0X

 The meaning of the last three raws is explained in my previous posting. I
confirm what I noticed about the overall purity.

 Looking at the events after a loose cut on the lepton we are getting a
gain of 36% with respect to the old production.
 Comparing the yields after all cuts the gain is 44%. We should have 500K
reconstructed B's in 85fb-1.


 GENERIC MC (just B0)
 --------------------

 Stat 23 fb-1 of B0 MC

 http://www.slac.stanford.edu/~daniele/vub/modesgen/sxModes-2.html DstarX
 http://www.slac.stanford.edu/~daniele/vub/modesgen/sxModes-4.html DcX
 and (actually crossfeed)
 http://www.slac.stanford.edu/~daniele/vub/modesgen/sxModes-3.html Dstar0X
 http://www.slac.stanford.edu/~daniele/vub/modesgen/sxModes-5.html D0X

 The B0 yield to seems scale properly with the data one (I should check
more carefully the per mode yields). The Bch's ones rapresent the
crossfeed.  The total amount of crossfeed should be of the order of the
2%.

 First example of history plots
 ------------------------------

 I also implemented the code to produce history plots for the basic
quantities normalized to the luminosity (to the total number of events for
the MC). At the moment only the breco yield plots are implemented. You can
find some examples here (the data subsamples are not perfectly in a
chronological order).

 http://www.slac.stanford.edu/~daniele/vub/historymc

  plots are (all divided by lumi [in pb-1] for data and by tot number of
events for MC)

  hist_lep.ps   mes plot after loose cuts on lepton
  hist_all.ps 	mes plot after all cuts
  hist_Dpi.ps 	mes plots for B->D*pi (Do->kpi), no cut
  hist_lumi.ps 	luminosity per sample (tot n events for MC)


 I am going to setup a web page with info and instructions to run all the
QA.
