Comparison between TOF survey data and tracking with associated TOF points. The following plots shows tracking data where the dimensions in x and y are the track positions at the TOF plane based on extrapolating the tracks all the way out to the TOF. The colored shadings are the x/y position of the track at the TOF with the color indicating which TOF paddle provided the tof point associated with the track. NO EXPLICIT TOF DATA ENTERS HERE! The horzontal lines indicate the location of the "nominal" TOF paddle positions. The profile data is the mean track position of all tracks along the paddles. AGAIN NO PADDLE DATA IS USED HERE OTHER THAN YES THE PADDLE PROVIDED THE HIT! The three large black dots indicate the location of the survey.
Shown are the data for survey points 1,2 and 3 which are along the horizontal axis between paddle 19 (last 3cm wide) and paddle 20 (first 4.5cm wide). These are above the beam hole. Q indicate the charge of the tracked particle.
The survey points are shown in the following picture

The first two plots below show the data below the beam line

The second two plots below are data from above the beam line

The next two plots are data from far below the beam line

And last but no least the two plots with far above the beam hole for both charges
