1. pedestals & status tables
   • input : L2ped output, new set every day, no BFC
   • processing Justin(IUCF) produces tables, Matt (MIT) uploads to DB
   • latency : 1 day, starts March20

1. BTOW Relative Calibration
   • method:
   relative gains
   • for every tower for every eta ring, Jan will produce muDst for 15 regular production runs: http://online.star.bnl.gov/RunLog/Summary.php?run=10088102 production2009_500Gev_c
   • input :1.4M minB events from dedicated run, needs BFC production
   • processing : fit slopes using BTOW Calibration Scott's method with integral driven limits of slope range, 2 days of work, WHO ? Scott?latency : 15 tar balls w/ muDst will be saved in HPSS, to be process in one pass on demand.
   • status : ( 7 May 2009 )
     • Jan
     has
     • created a .hist.root file *
     containing raw spectra for all barrel and endcap towers
     For each barrel tower,
     • Justin
     has
     • extracted slopes, a
     slope. A
     • large .pdf file shows
     the *
     • individual towers and
     their fitted
     • slope. There is also a much smaller .txt file which contains softID, slope, and slope error for each tower.
   • BTOW Relative Calibrationstatus 28 August 2009 : in limbo

1. absolute gains: assume maxET=60 GeV @ ADC=4076
   • assume eta-dependence =sin(theta) , NO confirmation of absolute scale from 2009 data
   • status 28 August 2009 : Matt looks at electrons from SL09b production
