[Average tower energy versus pseudo-rapidity]

Average calorimeter tower transverse energy as a function of the tower pseudo-rapidity in bins of the number of primary vertices, NPV. Data taken from 2011 with no trigger selection required (zero bias data). eps file gif file

[Tower energy distribution in central rapidity region]

Calorimeter tower transverse energy in two bins of the number of primary vertices, normalized to 1.0 in a central pseudo-rapidity region. Data taken from 2011 with no trigger selection required (zero bias data). eps file gif file

[Tower energy distribution in forward rapidity region] Calorimeter tower transverse energy in two bins of the number of primary vertices, normalized to 1.0 in a forward pseudo-rapidity region. Data taken from 2011 with no trigger selection required (zero bias data). eps file gif file

[Average tower energy distribution in central rapidity region as a function of the number of bunches in front of the last empty]

Average calorimeter tower transverse energy as a function of the distance from the last empty bunch in the current bunch train (DFE), binned in <μ>, for a forward pseudo-rapidity region. <μ> is the average number of interactions expected from the measured luminosity averaged over the luminosity block of the current event. At the beginning of the bunch train the mean tower ET is larger since the cancellation of energy deposits caused by the liquid argon calorimeter read-out has not yet completed when the next bunch begins to deposit energy. This effect is regarded as out-of-time pileup. The variation of the amplitude of the peak with <μ> is regarded as in-time pileup, as it depends on the conditions of the current bunch. Away from the beginning and end of the bunch train the is close to zero. eps file gif file

[Average tower energy distribution in central region as function of primary vertex multiplicity]

Average calorimeter tower transverse energy as a function of the number of primary vertices, NPV , in bins of <μ> for a central pseudo-rapidity region. Events are selected if they are located in a bunch that is at least 1μs away from the last empty bunch (DFE > 1μs). The mean tower energy in this region tends to decrease with increasing <μ>. eps file gif file
