aafit production new aafit production (cvs version v 0 r 2) MC with noise-summary files, Latest Trigger. Efficiency (-R, -C 2 -A) ARS-thresholds (for 9, 10, 12 -line data not final one yet) corsika / mupage / genhen-point in progress Data: after vetoing runs without any alignment and setups with 'SCAN': 313. 7 live-days available on sps see http: //www. nikhef. nl/~t 61/wiki/doku. php? id=march_2010_aafit_production Aart Heijboer ● awg april 2010 1

data/mc agreement Most quantities look good Remaining issue: lambda distribution of downgoing inclined tracks

data/mc agreement Most quantities look good Remaining issue: lambda distribution of downgoing inclined tracks ----- corsika - - - mupage vertical down : always good vertical up : always good diagonal down: sometimes ~ good, sometimes pretty bad data agree more with corsika in this respect than mupage.

data/mc agreement (diagonal events) -L slope position 5 line 10 10 line 9 line 3 10 12 line 10 3 clear evidence of time-dependence correlated to background rate and/or current (alignment) cannot fully explain problematic periods try to understand better by checking many distributions no smoking gun yet but extensive validation of many aspects of mc (see next slide) Aart Heijboer ● awg april 2010 3

data/mc agreement : a few distributions for 12 line/3 pe period 'conclusions' understanding of detector not perfect in all respects, but #hits in final fit #lines in now final fit time residual (ns) many aspects are quite well modeled will keep working some more, but probably not far away from final production data-mc differnece is often of same order as mupage-corsika could use current data & mc, if needed time residual (ns) for all periods: all 328 plots at: http: //antares. in 2 p 3. fr/users/heijboer/march-2010 Aart Heijboer ● awg april 2010 5
