** Description ** Module to calculate the commont time offset of the TOP detector. It selects two-track events, saves the bunch finder time offset in an histrogram and fits it to extract the global time offset with respect to the RF clock. It should be run in an individual job for each run, but in future it may be further authomatize to run on multiple runs in the same job. **Output** Root file containing: * The histogram of the bunch finder time offset * The fit function * The fit parameters ina tree format (usefuly when merging several files)

def event | ( | self | ) |
Fills the histogram of the time offset
Definition at line 169 of file cdst_calibrateCommonT0.py.
def getHistogramToFit | ( | self | ) |
Selects a histogram with the peak closest to histogram center
Definition at line 191 of file cdst_calibrateCommonT0.py.
def initialize | ( | self | ) |
Creates the histogram used for the commoT0 calculation, and takes the necessary objects from the DataStore
Definition at line 99 of file cdst_calibrateCommonT0.py.
def terminate | ( | self | ) |
Performs the fit of the bunch finder offset distribution, using a line + gaussian function. The results of the fit are saved in a tree
