Changes in AOD objects




Electron, Muon, TauJet are now also ‘multiple
collections’. Select collection of your choice by
StoreGate key from drop-down menu under
Atlantis AOD panel
Useful for csc12 AODs to compare Staco and
MuID Muons, or TauRec and Tau1p3p Taus.
(Most) Atlfast collections will be read by default if
available.
Please check dedicated page about running on
AODs, esp about JiveXML update:

EventView objects on Atlantis (1)

JiveXML can be called when running EventView
(tested with TopView). Instructions:
https://twiki.cern.ch/twiki/bin/view/Atlas/EventViewJiveXML



This will output ‘normal’ AOD data and EventView data.
EventView objects are currently filed under datatype
‘Composite Particle’ (panel under ‘AOD’). EventView
name can be selected there (e.g. collection RecoView)
All overlap-removed objects, and composite particle are
read, e.g. W and top, with EV number and labels
Many thanks to Akira Shibata !

EventView objects on Atlantis (2)

Objects from EventView are displayed in
‘AOD’-like fashion, in same colour coding. But symbols
not fully overlapping to allow direct comparison (“Which
ParticleJet was overlap-removed ?” “Which Electron
hasn’t passed preselection ?”)
In eta/phi projection as rotated squares
(AOD objects are circles)
 In rhoZ and XY projection as little towers outside detector.
Inner row: AOD, Outer row: EventView objects
 In Legoplot: Slim towers
 Widths/heights scaled to ET
Note: Associations with Track/Clusters still only possible for AOD
Electron/Muon.

EV obj. (3)




Display shows ttbar
event (csc12 5200)
Orange rotated
squares are
composite particles
– they have no
AOD equivalent.
Here: W and top
Upon ‘Pick’ on
objects, all
EventView labels
are printed out, e.g.
top
CompositeParticle = 6
storegate key:
RecoView
Pt = -124.495 GeV
E = 294.362 GeV
η = 1.506 Φ = 50.749°
Type = t (type code 6)
TypeEV =
EVCompositeParticle
Label = EV1_TopTopWithLeptonicW-

EV obj. (4)





Remember we always
had default
‘preselection’ for AOD
objects in Atlantis
(‘AOD->Cuts’ panel),
e.g. isEM.
Switching off those
default cuts, one can
see EventView
working (outer row of
towers):
None of Electrons
(green) and photons
(yellow) ‘good enough’
for preselection
Some ParticleJets
removed (pT cut),
some survive.
… and the new
composite particles
(orange) appear

Update on Trigger data



csc12 AODs now
have all L1/L2/EF
trigger info: item list
really large.
Item list in Legoplot
was rearranged,
new switch added:
‘Draw items’, to
avoid overlap of
legend and graphics.
Note: We’ve switched
off ROIs by default
now, as display looked
too full on start-up.
Switch back on in:
‘Data->Calo>EmTauROI/JetROI’
and ‘Data->Muon>MuonROI’ ‘

Other News


JiveXML being adapted for new EDM for release 13.0.0.
Some remaining issues (TriggerDecision), but mostly works
in nightly. Now broken-up in ‘package per detector’
(see Dec ’06 presentation in PAT meeting)
Running from ESD tested with 12.0.61 input, see
AtlantisWithAOD Twiki page (JiveXML update !)
Options:

athena.py optESDtoAOD.py JiveXML_ESDtoAOD.py RecExCommon_topOptions.py

Calorimeter: New option: ‘ATLAS->Geometry->Show
detector outline’: detectors not filled with colour. Esp useful
with ‘Calo->Colour by Energy’, to easily see ‘hot’ cells (red).
New layout option: 2x2 window,
Improved demo mode (Control Room)
TileCal commissioning: Click on cell to see ADC counts and
real pulse shapes
