Detailed Description

This module is the fitter for the CAF collector TOPLaserCalibratorCollector.

It analyzes the tree containing the timing of the laser and pulser hits produced by the collector, returning a tree with the fit results and the histograms for each channel. It can be used to produce both channelT0 calibrations and to analyze the daily, low statistics laser runs

calibrate()

CalibrationAlgorithm::EResult calibrate ( )

overrideprotectedvirtual

Runs the algorithm on events.

Currently, it always returns c_OK despite of the actual result of the fitting procedure. This is not an issue since this moduleis not intended to be used in the automatic calibration.

Implements CalibrationAlgorithm.

getCollectorName()

std::string getCollectorName ( ) const

inlineinherited

Alias for prefix.

For convenience and less writing, we say developers to set this to default collector module name in constructor of base class. One can however use the dublets of collector+algorithm multiple times with different settings. To bind these together correctly, the prefix has to be set the same for algo and collector. So we call the setter setPrefix rather than setModuleName or whatever. This getter will work out of the box for default cases -> return the name of module you have to add to your path to collect data for this algorithm.

Use calibration if you are fitting a large sample (1 M events or more) to derive a set of channelT0 calibrations. Use monitoring if you are fitting a smaller sample. The light path fractions and the tail parameters will be constrained according to the constraint file you passed to the fitter (usually teh result fo a high-statistics fit). Use MC to fit the MC sample and calculate a new set of prism corrections. No parameter is fixed, but the tail components are removed form the fit.
