Matching VELO tracks with tracks from the main tracker

Track segments from the VELO and from the Main Tracker (T1-T9) are matched. The efficiency for tracks with p<sub>true</sub>>5 GeV is found to be 99.10+/-0.04% with a wrong match fraction of 2.93+/-0.07%. Removing tracking station 1 decreases the performance only slightly. The efficien...

Sumario:Track segments from the VELO and from the Main Tracker (T1-T9) are matched. The efficiency for tracks with p<sub>true</sub>>5 GeV is found to be 99.10+/-0.04% with a wrong match fraction of 2.93+/-0.07%. Removing tracking station 1 decreases the performance only slightly. The efficiency decreases with less than 0.4%, while the wrong match fraction increases with the same number.
