I ran 5 events with pi- of energy 100 GeV. I tured ON the VTX, IT,TPC, and CAL.
I plot the "exact hit points" and came up with these plots.
A1. This is the x vs y plot of the "raw" hitpoints.
A2. This is the x vs z plot of the "raw" hitpoints.
A3. This is the y vs z plot of the "raw" hitpoints.
A4. This is the x vs y vs z plot of the "raw" hitpoints.

I ran the s4tpcanalysis and extracted the track hit points and came up with these plots.
B1. This is the x vs y plot of the track hitpoints.
B2. This is the x vs z plot of the track hitpoints.
B3. This is the y vs z plot of the track hitpoints.
B4. This is the x vs y vs z plot of the track hitpoints.

Observations:
1. From raw hitpoints, there were a total of 18, 587 hit points.
2. From the track hitpoints, there were a total of 3752 hit points.
3. Im confused why is it that the helical tracks observed from the raw hitpoints are gone in the track hitpoints.
4. Also, the track hitpoints stopped at z = -150 to 150.
Right now Im studying the URANUS analysis modules. I have not touched this part so far.
