- xinhu: [NaI bad block correction check]
- hyao: [RHRS New Acceptance and LHRS New Acceptance with New SAMC RZ generator]
xinhu:
- Correct most events back. But still not good for Box3.
hyao:
- 21612 has problem.
- Low energy Cross Section fluctuation < 3~4%.
- Left arm cross section is not good.
To do list:
xinhu:
- For NaI Eff, make geometry dependent cut efficiency(select pure electron sample) for NaI.
- Weight the event by this geo-dep eff when calculating the cross section.
- calculate the efficiency for bad block region(select the events in bad block region and add different E/P cuts to see the efficiency changing)
- pi rejection for low momentum .
- the efficiency for low momentum is a little complex than high momentum due to contamination of electron sample
hyao:
- Try 600,700 Acceptance. See the difference.---->For right arm, Beam Left Fe, 4 acceptance. 100-200,200-300,300-800,>800. For Beam Right Fe,4 acceptance, 100-200,200-300,300-400,>400. --hyao 11:40, 19 April 2011 (UTC)
- For low energy, 300-400 MeV, fix the highest point for xs.---->Done. --hyao 11:40, 19 April 2011 (UTC)
- last three runs for 739 R Fe 60, fix the highest and lowest points.---->Done. --hyao 11:40, 19 April 2011 (UTC)
- For left arm, at high energy, we might be not necessary to use NaI E/p and Geo Cut.
- For left arm low energy, first get 3 points cs, Then remove NaI E/p and Geo Cut to compare it.
- Continue "To do list" in March 31 2011 Meeting Summary
