This page summarizes the status of the noisy/hot spots reported by the offline Data Quality monitoring of Jets and EtMiss.
At present, it focuses on Jets before and after reprocessing of ATLAS 2009 collision data.
Note that it does not cover every items in JetMETcpdq savannah bug tracker so far.
Attached Jet 2-D occupancy plots in animated gifs (updated every 2 secs):

[Tile old tag of noise DB] Will be fixed
* Savannah 62547 (open->closed at 11-02-2010)
* Eta and phi: [+0, -1.67], [-0.55,-2.65], [+1.15, +2.85]
* Express stream, AntiKt4H1TopoJets
* Shown in Feb'10 reprocessing test: Run 142383
* Also shown in other runs with solenoid/toroid ON reprocessed: Run 142191, 142193, 142195, 142165
* Clearly shown in CaloMonitoring (Of course, also shown in Jet)
* Reported by Tile in reprocessing test sharepoint signoff
* Also shown in all cosmic runs in early Feb, 2010

[No title] Chasing up
* Reported in DP/DQ meeting (09-Feb-2010)
* Eta and phi: [+0, -1.7]
* Express stream: AntiKt4H1TopoJets
* Apparently shown in Feb'10 reprocessing test since other tile noise issues are gone: Run 141994
* Couldn't check 142065 with similar condition (solenoid/toroid OFF) because of no express stream reprocessed
* Tile speculated as the cause of this: A masked hot cell can be a bad neighbor to dead cell for energy correction. This feature may be leading to jets seeing a hot cell while Tile does not.
* TIle experts are confident that it is not caused by Tile because of the absence of the hot spot in the CaloMonitoring (05-Feb-2010)

141994_JetEtaPhiTopoSummary_Feb10reproTest.png

[HECC noise at -1.8,1.9] Under investigation
* Savannah 62550 (open)
* Eta = -1.75 ~ -1.85 (?), and phi = +1.91
* LAr channels: FT3/Slot6/ Ch.98 (first suspected), Ch.114 (later), Ch.97 (now)
* LAr savannah: 60820
* ELog: 65918/65922/73183 (Trigger) and 66140 (JetEtMiss offline DQ)
* Express stream: AntiKt4H1TopoJets
* Found in Tier-0 proccessing: Run 142191
* Still shown in Feb'10 reprocessing test
* Also shown in a cosmic run in early Feb, 2010
