Overview Introduction Results Conclusions and Outlook Backup slides Alignment settings 2 / 17

Introduction Following this page, I show some raw plots from the very first (successful?) alignments using MP on CRAFT09 data at 3.8 T. Some remarks valid for all following slides: ◮ Number of events are those reported by mps stat.pl unless stated otherwise ◮ Version used was CMSSW 3 2 2 patch2 ◮ 1M of events used (3.8 T) ◮ For configs see backup slides for details 3 / 17

Conclusions and Outlook ◮ Alignment seems not satisfactory, i.e. can’t reproduce results from misalignment study (see Alignment meeting of Jul 23) Plans: ◮ Improve alignment to achieve at least what CRAFT08 did ◮ Full alignment – how much data do we need for this? Config? 7 / 17
