[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).

[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

[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 <&#956;>, for a forward pseudo-rapidity
region. <&#956;> 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 <&#956;> 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 <ET> is close to zero.

[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 <&#956;> for a central pseudo-rapidity region. Events are selected if they are
located in a bunch that is at least 1&#956;s away from the last empty bunch (DFE > 1&#956;s). The
