Fig.0 Mass spectrum for signal and for accidental coincidences. Mass cut:[0,1.3] for run 47422
hcer_npe.lt.0.5 and haero_sum.lt.2.5 and ssshsum.gt.0.6 and a clever cut on cointime.vs.hsbeta illustrasted in Fig.10 of our previous discussion, we get the mass spectrum of omega for signal cut and accidental coincidences cut seperately. The figure looks like the following:

Fig.0 Mass spectrum for signal and for accidental coincidences. Mass cut:[0,1.3] for run 47422 |
Hence the Yield of Proton for this run is Nexp=9692-2064/3=9006.
We can use the similar discussion, but make a tight missmass cut (missmass-0.785).lt.0.033 to make the same disscussion.
And we get the Yield of Proton for this run is nexp=1768-182/3=1707.
Note that we use Nexp to stand for the number of wide missmass cut while use nexp to stand for the number of narrow missmass cut.
Qtotal=303637 mC. (using BCM2)
hfid=0.9622,
HMS computer dead time HCDT=3.12%
HMS electronics dead time HEDT=0.76%
sfid=0.9826,
SOS electronics dead time SEDT=0.11%
Our haero_sum and cointime cut HCour=0.98.
Hence Qeff= Qtotal*(hfid*(1-HCDT)*(1-HEDT)*sfid*(1-SEDT))*HCour
=270188 muC.=270.188 mC.
Note that HCour is the efficiency caused by our Hareogel cut and cointime cut. It is not included in any efficiency reported in scaler files, so we added it here. Later we will use nexp/Qeff or Nexp/Qeff to check run by run.
Table.1 Nexp, nexp,Qeff for different runs. Nexp/Qeff(net)= Nexp/Qeff(LH2)-Nexp/Qef(dummy)*0.25/1.96 where the 0.25 mm is the thickness of Al shell of LH2 target and 1.96 (mm) is the thichkness of "thick dummy). We combine run 47452 and 47453 and think Nexp/Qef(dummy)=32.5+-0.7. Similar thing is for nexp/Qeff(net) calculation.

Fig.10a Proton Yield for different runs. Here we have a missing mass cut:[0.0,1.3]. The errorbar are statistical error bar. THis is for runs which have Q2=1.6, Phms=2.931, Ebeam=4.709, thetahms=16.29, thetasos=25.735 and Psos=1.65. |
Fig.10b Proton Yield for different runs. Here we have a missing mass cut:[0.752,0.818] which is a 3 sigma cut around omega mass. The errorbar are statistical error bar. THis is for runs which have Q2=1.6, Phms=2.931, Ebeam=4.709, thetahms=16.29, thetasos=25.735 and Psos=1.65. |
Table.11 Nexp, nexp,Qeff for different runs. Nexp/Qeff(net)= Nexp/Qeff(LH2)-Nexp/Qef(dummy)*0.25/1.96 where the 0.25 mm is the thickness of Al shell of LH2 target and 1.96 (mm) is the thichkness of "thick dummy). We combine run 47737 and 47738 and think Nexp/Qef(dummy)=76.0+-1.1. Similar thing is for nexp/Qeff(net) calculation.

1. In fig.4, run 47367 seems still not normal
I checked the records. It says that run 47367: "roc2 dead run ended". So it was ended with some detector
dead at it's end. For this run, maybe at least the first half of the events should still be usable.
2. Fig.7 a or b. is normal now.
In the mean while, I find the calibration file of run 47693 needed to be modified. The same problem as before. This has been corrected in the above analysis.
