Atmospheric Neutrino Software Update Andy Blake Cambridge University Thursday December 7th 2006
AtNu Ntuples • Contained vertex atmospheric • neutrino analysis carried out • using AtNu Ntuples. • – Ntuple classes in AtNuEvent • package (class structure right). • – Ntuples filled using NtpMaker • module in AtNuOutput package. • – Documentation in doc-db #2361. • – Event display and analysis tools • provided by AtNuUtils package. • [B. Speakman]. Andy Blake, Cambridge University AtNu Software Talk, slide 2
AtNu Short Ntuples • AtNuAna package in CVS distills important physics analysis • variables from AtNu Ntuples into lightweight ROOT ntuples. • – no dependencies other than on ROOT itself. • Information contained in short ntuples: • Reconstruction • Every reconstructed track. • Overall shower information. • Summary of strip information. • Summary of veto shield information. • Data/MC • Basic event information. • Data quality monitoring. • Beam monitoring. • MC truth. Event Selection Event topology variables. Event kinematics variables. Event selection variables. Event Type Event Containment (FC/PC). Event Direction (UP/DN). Cosmic Muon. Multiple Muon. Beam Spill. Andy Blake, Cambridge University AtNu Software Talk, slide 4
AtNu Short Ntuples • Have generated AtNu short ntuples for all far detector data • between August 1st 2003 and February 28th 2006. • – 40M events. • – 600Mb/month. • Enables easy introduction to far detector physics analyses. • – Atmospheric neutrinos. • – Upward-going muons. • – Cosmic-ray muons. • – Beam neutrinos. • See http://www.hep.phy.cam.ac.uk/minos/atnu_ntuples/ Andy Blake, Cambridge University AtNu Software Talk, slide 5
