3. CM23 Harbin January 2009TOF Reconstruction3 New applications ●New applications in development (but already useful!): ■TofMonitor ►Space point/time-of-flight/momentum reconstruction at a glance ►Are all the PMTs broken and how/correctly cabled? ■TofCalibration ►Calibrating the TOFs for cable length and testing this calibration ►Plane-plane time-walk and station-station calibration in development ■TofEmittance ►Plot x-x’ and y-y’ trace space ►Calculate emittance ●These are uploaded to G4MICE and easy to use ■Histograms automatically thrown to the screen and fill up as you run ■How to run them ►./Executable cards.in datafiles ►./TofCalibration cards.in 885.000 ►./TofMonitor cards.in Digits.out.gz ►./TofEmittance cards.in 8{79..81}*

4. CM23 Harbin January 2009TOF Reconstruction4 New datacards ●Old required datacards: ■Model ►New more accurate models required though! ●New datacards: ■TofCalibrationMode ►0 – Use existing calibration, and reconstruction cuts ►1 – Disregard calibration (in order to make a new one) and disregard reconstruction cuts ■FileTag ►String to include in the various root/text/picture output files
