  1. METHOD K-factors EE EB Lower energy threshold as a function of ring index.

  2. Correction for tracker material and SM edges (NEW) To be added in PAS

  3. Variation of the intercalibration precision with statistics Variation of the intercalibration precision with 1/sqrt(N) for one pair of rings in the barrel. Intercalibration precision which can be obtained with 25 million events and the limit in the calibration precision as a function of h TO DO In EB try to introduce correction for tracker material and SM edges Same plot for EE

  4. Relative SM scale Relative supermodule scale vssupermodule index determined with the first 2010 data Onlyf-sym Correlation between 2009 and 2010 results. TO DO Produce new Sm scale and study the statistical uncertainty on v9 sample (160M evt) divided in 10 samples

  5. Study of the systematics Calculated sm scale vs. the inverse of the applied miscalibration Residuals of the calculated scale coefficients from a linear fit TO DO Study to be repeated on MC-SPRING10 data (7TeV)

  6. The alca stream Rate of event logging for the alca/phisym stream and rate of accepted events Selection = goodcoll selection To be understood
