Understanding the data - a first off-line

EUSO-BALLOON Analysis Meeting, October 2-3 2014 2

Global lookAll 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

ETOT data Structure4 Trees :

tevent : Event packet tree (physically oriented) One entry is one GTU

televent : Event packet tree (electronics oriented) One tree entry is one packet

texp : Experiment information tree (detector description)

tdataflow : Hardware data flow tree (CPU messages)

No information is lost from raw data to ROOT data !!!

Packet number

Not very usefull, several packets could have the same number

EUSO-BALLOON Analysis Meeting, October 2-3 2014 9

Trigger time uniformity ?

S-Curve flat , probably OK, why peak on cputrigger

Why isThere thisBump inCpu trigger ?

Also smaller bumpIn acquisition

Unit inMicrosecond ?

EUSO-BALLOON Analysis Meeting, October 2-3 2014 10

What is the exact definition ofAn event-life time,Can we understand why it is differentFor the various types of runs ?

EUSO-BALLOON Analysis Meeting, October 2-3 2014 11

What is the definitionOf the dead time.

Why this two structure

How it intervene 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 ?

Which so differents ?

KI Data

KI see high signals on acquisition mode

I thought it wasSwitched off

EUSO-BALLOON Analysis Meeting, October 2-3 2014 19

Correlation PC-KI data

KI data vs PC data

Use these plots to « trigger » on interesting GTU

What is wrong what is correct ?
