TOF Efficiency

In order to estimate the efficiency of the TOF charged tracks are used that hit the TOF wall. For such tracks the closed TOF point to the track point is obtained and the distance to this point is recorded as a function of track momentum an in bins of 9cm x 9cm in x and y at the TOF wall. This is done for both DATA and MC:

  1. DATA(left) MC(right) TOF point match to tracks for bin 15/20:

  2. For both DATA and MC a cut a 9cm is applied to calculate the efficiency to find a matching TOF point for the track.
    This is done for 30 bins in x and y and shown in the following 2d plots(data/mc):
