Refine BF syst FSR DCSD table
Message from Werner:
No, we are not looking at central values at all -- just the errors on the fit parameters. Let's take BrD2KPi as an example. regular = 0.000771274 variation1 = 0.000689192 variation2 = 0.000765497 variation3 = 0.000682723 So, experimental syst = variation 3 = 0.000682723 FSR syst = sqrt( regular^2 - variation1^2 ) = 0.000346234 DCSD syst = sqrt( regular^2 - variation2^2 ) = 0.000094223 Notice that if you add all three in quadrature, you get back to the regular error.

Ander's comments about the double tag fits
Thanks for doing these fits, I looked at the results. At most it would have increased the yields by ~0.1%. However, this did not seem to systematically increase the yields. Maybe this is beause there is less signal in these 'outlier' runs. Hence I think that the effect of this is less than 0.1% and at this point I think that we can just ignore this. I.e. we should stick to the results as we have them in the PRD draft so far.
Mordify the efficiency for pi0 and PID
These efficiencies needs to be corrected for PID and pi0 finding efficiencies.
- Re-run the BF fitter Backup the original result:
cp -r regular regular0
Werner had added new sections.
dhad bf regular1
dhad table compare bf regular1
Same results.
So, refresh the regular fits:
dhad bf
Under the section: "Corrected efficiencies":
dhad table prd_dt_dz_eff_yield ... Just the central values
dhad table prd_dt_dp_eff_yield ...
dhad table prd_st_eff_yield ...

Add Bad Run description in CBX
From Peter's posing on HyperNews:
Run 208087 in data37 has, we think, an incorrect beam energy. It is reported as 1.87679 GeV, while it is surrounded by runs at 1.88679 GeV. Checking the logbook, it appears that the beam energy was manually input for this run, and it's probably more likely that a digit was entered wrong than that CESR dropped 10 MeV for one run.
Added in.
Update the final result in CBX
OK.
check in CBX 1.75
