  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 !!!

  7. Packet time distribution Helicopter UTC Times: 0:03 2:50 5:36 7:00 08:23 1:26 4:13 UTC time since 1970 January 1st 00:00:00 EUSO-BALLOON Analysis Meeting, October 2-3 2014

  8. Packetnumber Not veryusefull, severalpacketscould have the samenumber EUSO-BALLOON Analysis Meeting, October 2-3 2014

  9. Trigger time uniformity ? Whyis There this Bump in Cpu trigger ? Alsosmaller bump In acquisition Unit in Microsecond ? EUSO-BALLOON Analysis Meeting, October 2-3 2014 S-Curve flat , probably OK, whypeak on cputrigger

  10. What is the exact definition of An event-life time, Can we understand why it is different For the various types of runs ? EUSO-BALLOON Analysis Meeting, October 2-3 2014

  11. Whatis the definition Of the dead time. Whythistwo structure How itintervene in the flux calculation ? EUSO-BALLOON Analysis Meeting, October 2-3 2014

  12. CPU time vs CLKB time • CPU time provides the CPU time in • UTC second ! • Clkb time unit is in what ? • Clkb time is reset ? When ? EUSO-BALLOON Analysis Meeting, October 2-3 2014

  16. Photon count data histograms Whichsodifferents ? counts EUSO-BALLOON Analysis Meeting, October 2-3 2014 Acquisition seams to be sensitive to high signal above count 170

  17. PC data vs ASIC thresholds EUSO-BALLOON Analysis Meeting, October 2-3 2014

  18. KI Data I thoughtitwas Switched off EUSO-BALLOON Analysis Meeting, October 2-3 2014 KI seehighsignals on acquisition mode

  19. Correlation PC-KI data KI data vs PC data Whatiswrongwhatis correct ? Use these plots to « trigger » on interesting GTU EUSO-BALLOON Analysis Meeting, October 2-3 2014

  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
