The following plots are for muon events (selected in Kmu2Analysis()) and show the time difference (in ns) between the KTAG beam signal and signals in the GTK, Straws, RICH , CHOD, LKr and MUV3.
Fig. 1 GTK - KTAG rms 0.1244 ms
Fig. 2 STRAWS - KTAG rms 4.65 ns
Fig. 3 RICH - KTAG rms 0.1602 ns
Fig. 4 CHOD - KTAG rms 0.2611 ns
Fig. 5 LKr - KTAG rms 1.4 ns
Fig. 6 MUV3 - KTAG rms 0.4811 ns
Fig. 7 p-value distribution P-value for chi**2 of time difference between GTK, Straws, RICH ,LKr ,CHOD and the KTAG. The distribution is flat, as expected, with evidence of miss-timing for ~ 20 % of tracks.
Fig. 8 p-value distribution As Fig 7 but with log plot.
To indicate the origin of the low probability peak in Figs. 7 and 8, the following plots show the p-value plots for the individual detectors.
Fig. 9 p-value distribution GTK: no significant time problems.
Fig. 10 p-value distribution Straws: no significant time problems.
Fig. 11 p-value distribution RICH: ~2% time error.
Fig. 12 p-value distribution CHOD: ~20% timing problems.
Fig. 13 p-value distribution LKr: ~2% timing problems.
