- TPC - Gene reported slewing correction for clusters is in DB. T0 should be in DB at the end of the week. Then we can ask for re-production of one fill to see if tracking efficiency improved at Z~0
- PPV - status of evaluation of SL09b production - no report
- Vernier scan - Ross
- was found missing factors in the formula computing BBC xsection, for low lumi fill in pp500 computed xsection is 26mb - close to the value know for pp200
- Q: what do we expect for BBC xsection at 500 GeV - answer is unknown
- the linear formula can't be applied for regular fills when BBC is saturated, Hal suggested using more advanced approach counting bXings w/o rate, using zero of Poisson distribution. LINK SHOULD BE HERE
- BHT3 x-section : results of fit with noisy patches removed Conclusion: background reduces but not vanishes. Comparison for other vernier scan will be made, estimation of error in determination of xSection due to non vanishing background will be made
- BTOW final 5% calibration, needed to release Jacobian peak vs. ET.
- relative -Joe - link , is completed. Write-up sent to emc2-hn for critique.
- absolute -Matt, will be performed shortly using Joe's relative gains.
