Residual distribution in x, integrated over all hits-on-tracks in the pixel barrel for the nominal geometry and the preliminary aligned geometry. The residual is defined as the measured hit position minus the expected hit position from the track extrapolation. Shown is the projection onto the local x coordinate, which is the precision coordinate. Tracks are selected to have pT > 2 GeV, |d0|<50mm, |z0|<400mm (in other words they are required to go through the pixel L0). The distribution is shown for 5 cosmic runs: 91885, 91888, 91890, 91891, 91900, all have solenoid on - corresponding to ~25% of all the solenoid-on data taken in Sep/Oct 2008. New Tracking is used with material interactions-on (in 14.5.0). A double Gaus fit is performed but only the mean and sigma of the narrower Gaus are shown. |

Residual distribution in y, integrated over all hits-on-tracks in the pixel barrel for the nominal geometry and the preliminary aligned geometry. The residual is defined as the measured hit position minus the expected hit position from the track extrapolation. Shown is the projection onto the local y coordinate, which is the non-precision coordinate. Tracks are selected to have pT > 2 GeV, |d0|<50mm, |z0|<400mm (in other words they are required to go through the pixel L0). The distribution is shown for 5 cosmic runs: 91885, 91888, 91890, 91891, 91900, all have solenoid on - corresponding to ~25% of all the solenoid-on data taken in Sep/Oct 2008. New Tracking is used with material interactions-on (in 14.5.0). A single Gaus fit is performed. |
