  • Pedestals were determine from run1001, by fitting Gaussian to the maximum +/- 4 channels. This time I know how to store pedestals to DB. (details)
  • Event selection is described also there . Example of spectra for the same tower (06TD05 at X=9 on the lower plots) for different timing is below. The fit range was not change on purpose to see what the dummies algo does. The table with fit params and all spectra are at the bottom of the page.

  • Exponential slope for eta bin =5
    Shaded area represents carte 4, crate 3 is on the left, crate5 on the right.

  • Gaussian mean of the MIP 'efficiency' for eta bin =5
