  1. Understanding the data - a first off-line look Sylvie Dagoret-Campagne EUSO-BALLOON Analysis Meeting, October 2-3 2014

  2. Global look • All packets over all runs, • Try to understand the meaning data in the ROOT file, • Try to understand the distribution of these data (expected or strange) • Try to identify bugs or good data EUSO-BALLOON Analysis Meeting, October 2-3 2014

  3. How itisdone .ROOT data .DAT data ScurvesMerged Scurves SCurves SCurves ETOT Ana ETOT Acquisition Merged Acquisition Acquisition CPU-Trigger Merged CPU-TRIGGER CPU Trigger EUSO-BALLOON Analysis Meeting, October 2-3 2014

  4. ETOT data Structure 4 Trees : • tevent: Event packettree (physicallyoriented) • One entry is one GTU • televent : Event packettree (electronicsoriented) • One tree entry is one packet • texp : Experimentinformation tree(detector description) • tdataflow : Hardware data flow tree(CPU messages) No information islostfromraw data to ROOT data !!!

  20. Quick analysis of the tree in a ROOT macro Used in the plots usedpreviously EUSO-BALLOON Analysis Meeting, October 2-3 2014

  21. Data structure for a more refined analysis • Seenext EUSO-BALLOON Analysis Meeting, October 2-3 2014

  22. Data structure in memory to get the data from the tree To retrieve info like in standalone-event-dump Claudio code structcpu_packetpacket_; structpayload_full_eventpayloadfullevent_; structccb_eventccbevent_; structclkb_eventclkbevent_; structpdm_eventpdmevent_; UShort_t gain_[MAXCCBCOUNT][MAXPDMCOUNT][2304]; UShort_tpc_threshold_[MAXCCBCOUNT][MAXPDMCOUNT][36]; UShort_tki_threshold_[MAXCCBCOUNT][MAXPDMCOUNT][36]; UShort_tframe_header_[MAXCCBCOUNT][MAXPDMCOUNT][34]; To readteventtree (one GTU per tree entry) UChar_tdataphys_[MAXCCBCOUNT][MAXPDMCOUNT][MAXPDMPIXNUMX][MAXPDMPIXNUMY]; UChar_tki_dataphys_[MAXCCBCOUNT][MAXPDMCOUNT][MAXKICOUNT]; To readteleventtree ( one packet per tree entry) UChar_tdatael_[MAXCCBCOUNT][MAXPDMCOUNT][MAXGTU][MAXPDMPIXNUMX*MAXPDMPIXNUMY]; UChar_tki_datael_[MAXCCBCOUNT][MAXPDMCOUNT][MAXGTU][MAXKICOUNT]; EUSO-BALLOON Analysis Meeting, October 2-3 2014
