Hcal Noise Plot List for Approval

This is a collection of plots potentially to be approved/used in talks. In principle I try to include only stuff that we are using. "To be collected" means that I have yet to copy it from the note to here.

• Distribution of R45 is in the baseline filter section

Noise Trend

Item	Description	Image	Comment
Noise trend	Rate of different noise types (and threshold) as a function of run number		These are plots made from Offline Hcal Noise monitoring, from the 2011 Cosmics (interfill) and 2012 Cosmics (interfill). These plots contained runs up to November 27, 2012.

RBX Noise vs Met Threshold

Item	Description	Image	Comment
RBX Noise Rate vs. MET Threshold	RBX Noise Rate vs MET Threshold for run 195429 - November 13, 2012		RBX Noise Rate vs MET Threshold for run 195429 - November 13, 2012

HBHE Baseline Filter

Item	Description	Image	Comment
Basic distributions	1D distributions of variables used in the noise summary object		Not found in the note
R45 distribution	2D distribution of R45 as a function of RBX energy, including cut positions (offline, HLT)		Need to be polished and add cut positions, and add more data
Pileup dependence	Distributions as a function of PV count		Not found in the note
MET comparison	MET for all events and MET for good events		To be collected

HBHE Fit-based Filter

Item	Description	Image	Comment
Basic distribution	Discriminant vs. pulse energy		To be polished
MET1D	1D distribution of all events and cleaned events		To be collected
MET2D	MET before cleaning vs. after cleaning		To be collected

LASER Event	Example of a LASER event

Hcal Laser Filtering

Item	Description	Image	Comment
HF Calibration Multiplicity	Number of HF Calibration Digi channels vs. Number of HF Digi Channels in /JetHT/Run2012C-v1/RAW dataset. Dashed pink line indicates default cut threshold used to remove events with excess digi channels.
HBHE Calibration Multiplicity	Number of HBHE Calibration Digi channels vs. Number of HBHE Digi Channels in /JetHT/Run2012C-v1/RAW dataset. Only calibration channels with > 15 fC in time slices 3-6 are considered. Dashed pink line indicates default cut threshold used to remove events with excess digi channels
HBHE laser/non-laser RBX occupancy	Fractional occupancy of the 3 HBHE RBXes that do not receive proper laser signals ("bad" RBXes) vs. fractional occupancy in the remaining ("good") RBXes in /JetHT/Run2012C-v1/RAW. Events below and to the right of the dashed pink line are rejected by the default laser filter.
HBHE laser multiplicity	HBHE calibration digi vs. HBHE digi distribution for events failing the RBX fractional occupancy cut in /JetHT/Run2012C-v1/RAW. The RBX cut almost completely removes the high-occupancy tail from the HBHE Calibration Multiplicity plot.
HO Calibration Multiplicity	Number of HO calibration Digi channels vs. Number of HO Digi Channels in /JetHT/Run2012C-v1/RAW dataset. No evidence of HO laser contamination is seen.
HF RADDAM map	ieta-iphi map of (blue) HF RADDAM channels, (green) channels neighboring the RADDAM cells, and (red) channels mirrored in ieta from the RADDAM channels.
RADDAM vs. Neighbor	Fractional occupancy of RADDAM channels vs. fractional occupancy of neighboring channels in /JetHT/Run2012C-v1/RAW. No evidence of RADDAM events (which have RADDAM fractional occupancy near 1 but neighboring fractional occupancy much less than 1) is seen.
RADDAM vs. Mirror	Fractional occupancy of RADDAM channels vs. fractional occupancy of ieta-mirrored channels in /JetHT/Run2012C-v1/RAW. No evidence of RADDAM events (which have RADDAM fractional occupancy near 1 but mirrored fractional occupancy much less than 1) is seen.
Jet 2012A HBHE Laser Rate	HBHE Laser Rates in /Jet/Run2012A-v1/RAW dataset.
Jet 2012A HF Laser Rate	HF Laser Rates in /Jet/Run2012A-v1/RAW dataset.
JetHT 2012C HBHE Laser Rate	HBHE Laser Rates in /JetHT/Run2012C-v1/RAW dataset.
JetHT 2012C HF Laser Rate	HF Laser Rates in /JetHT/Run2012C-v1/RAW dataset.
