Detailed Description

EM calorimeter gap corrections.

This tool attempts to correct for the energy lost in dead material in the gap between the barrel and end cryostats. In addition to the energy in the EM calorimeter, we also use energy deposited in scintillators between the cryostats. The correction is of the form

\[ E' = A(E_c + \alpha E_s), \]

where \(E_c\) is the measured energy in the EM calorimeter, and \(E_s\) is the measured energy in the scintillator. The coefficients \(A\) and \(\alpha\) are \(\eta\)-dependent. The total scale \(A\) is determined by fitting a polynomial to the \(E_{\rm meas}/E_{\rm true}\) curve outside the gap region, and interpolating over the gap. The weight \(\alpha\) is found by requiring that the RMS of \(E'\) be a minimum.

The resulting weights do not vary a lot with energy in the range studied (50 to 200 GeV). Thus, we combine together all the energies when determining the correction; the resulting correction is then energy-independent. The residual energy dependence will be folded into subsequent corrections.

Many of the corrections use the same method for doing the final interpolation in energy.

Perform energy interpolation.

We factor out this common code here. builder is used to construct the interpolation table; energy is the energy value for the interpolation. energies is the list of energies at which we have tabulated values, and energy_degree is the degree of the polynomial interpolation in energy.

Parameters

energy	The energy value for the interpolation.
builder	Helper to construct the interpolation table.
energies	The energy interpolation table.
energy_degree	The polynomial interpolation degree for the energy interpolation.

Many of the corrections use the same method for doing the final interpolation in energy. We factor out this common code here.

toolType()

virtual const std::string& CaloUtils::ToolWithConstants< CaloClusterProcessor >::toolType ( ) const

virtualinherited

Return the name of the type of this tool.

A saved set of constants includes both the C++ class name and a version number. Normally, the class name is taken from the Gaudi type() method, but that may be changed by overriding this method. This can be used, for example, when there are tools with distinct C++ classes but which are yet similar enough to combine together.

toolVersion()

virtual int CaloUtils::ToolWithConstants< CaloClusterProcessor >::toolVersion ( ) const

virtualinherited

Return the version number for this tool.

A saved set of constants includes both the C++ class name and a version number. The idea is that the version number can be bumped whenever there's a backwards-incompatible change; this gives some protection against trying to use an old version of a tool with an incompatible newer set of constants.

If you want a tool to have a version number, override this method. Otherwise, it will default to a version number of 0.

writeConstants()

virtual void CaloUtils::ToolWithConstants< CaloClusterProcessor >::writeConstants ( std::ostream &  stream, const std::string &  name, const EventContext &  ctx  ) const

virtualinherited

Dump method (for debugging)

Parameters

stream	Ostream to which to write.
name	Name to go in output
ctx	Event context.

If true, then this is a dummy tool that should not be executed.

This is used for the case of reading from COOL using hierarchical tags: we need to have such tags associated with some object in each folder, regardless of whether or not the correction from that folder is actually used. [Every folder that IOVDbSvc knows about at configuration time needs to have a valid object for the configured tag, else IOVDbSvc will raise a fatal error. But we don't know at configuration time which folders we're actually going to need, so we gotta configure all of them.]
