Detailed Description

EM calorimeter \(\phi\) modulation corrections.

The energy response of the calorimeter varies slightly depending on the position of the particle impact in \(\phi\) relative to the accordion structure. We try to remove these modulations as best we can. This is a small correction (< 1%). We're further hampered in doing a good job by the fact that the wavelength of these modulations in \(\phi\) is on the order of a few mrad, which is similar to the \(\phi\) resolution. This leads to the modulations being washed out.

Nevertheless, we proceed by plotting the ratio \(E_{\rm meas}/E_{\rm true}\) vs. the \(\phi\) offset within an absorber, all binned in \(\eta\). (In order to get the modulations to show up, when making the profile plots, you need to plot the peaks from Gaussian fits to the distributions, not the means.) In each \(\eta\) bin, we then fit a 2-term Fourier series, parametrized like this:

\[ 1 + A\left[\alpha\cos(N\phi+C) + (1-\alpha)\cos(2N\phi+D)\right], \]

where \(\alpha = \tan^{-1} B/\pi + 1/2\) and \(N\) is the total number of absorbers in \(2\pi\) (either 1024 or 768).

The correction is tabulated at several different energies; we then do a final interpolation in energy to find the final correction. (Note, however, that the observed energy dependence seems to come mainly from the energy dependence of the \(\phi\) resolution. It would be better to separate out this effect in a future version.)

These corrections are presently done before the gross energy corrections, done later. But in order to get decent results out of the energy interpolation done here, we need to get a better estimate of the energy. So we have a crude response correction built-in here, which is used to correct the cluster energy for the purpose of energy interpolation. (This can hopefully be removed in a future version which does the corrections in a more logical order.)

◆ 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.

◆ m_isdummy

Constant<bool> CaloUtils::ToolWithConstants< CaloClusterProcessor >::m_isdummy

privateinherited

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.]
