Entry number 353587

Here is the latest on B triple coincedence (Runs 3026-3123).
The cuts We're using were revised by myself and Shalev to get the "best"
events we can get and trust.


We estimate about 46 events with no delta cut and ** evetns when we do
include the delta cut.

The 3rd plot shows the delta cut we did. (smaller then 1.06 and -88)
We know that it's not the best one that there is but it's the best we
could come up with for now.




We're now cuting on:
1) L-HRS vertex.
abs(L.gold.y[0]/sin(20.3*3.14/180.))<0.08

2) R-HRS vertex.
abs(R.gold.y[0]/sin(-29*3.14/180.))<0.08

3) L&R HRS Vertex difference.
abs(L.gold.y/sin(20.3*3.14/180)-R.gold.y/sin(-29.*3.14/180))<0.03

4) Basic PID in BB.
sqrt(BB.tp.e.LE[%d]*BB.tp.e.RE[%d])>400 &&
sqrt(BB.tp.de.LE[%d]*BB.tp.de.RE[%d])>150

5) Re-timing.
abs(BB.tp.e.tof[%d]+354)<7 && abs(DBB.t3[0]-390)<230

6) No EDTM.
DBB.edtpr[0]==0

7) Track in L&R HRS.
abs(L.gold.dp[0])<0.05 && abs(R.gold.dp[0])<0.05

8) Delta
atan2(SK.Prec_x[0],SK.Prec_z[0])*180/3.14<-88 && SK.Mrecoil[0]<1.06
