Detailed Description

Class that allows to split runs into the intervals of intended properties given by the lossFunction.

It typically avoids of having large time gaps within calibration intervals. The algorithm is based on minimizing the total loss function Notice, that the calibration interval is defined as a map, where for each run the included period is defined by the start and end time

◆ createAtoms()

std::vector<Atom> createAtoms	(	const std::vector< std::pair< double, double >> &	atomsTimes,
		const std::vector< Evt > &	evts
	)

inlineprivate

Get the vector with parameters of the calibration Atoms.

Parameters

atomsTimes	vector with start/end times of the atoms
evts	vector with events

Returns: A vector of atoms, each including start/end times and the number of events inside

Definition at line 260 of file Splitter.h.

◆ getBreaks()

static std::vector<double> getBreaks ( std::vector< std::map< ExpRun, std::pair< double, double >>> res )

inlinestatic

Get vector with breaks of the calib.

interval

Parameters

res	A single calibration interval

Returns: : Vector of times [hours] of the break points, i.e. the subintervals boundaries

Definition at line 131 of file Splitter.h.

◆ getIntervals()

std::vector<std::vector<std::map<ExpRun, std::pair<double, double> > > > getIntervals	(	const std::map< ExpRun, std::pair< double, double >> &	runs,
		std::vector< Evt >	evts,
		TString	lossFunctionOuter,
		TString	lossFunctionInner,
		double	atomSize = `3. / 60`
	)

inline

Function to merge/divide runs into the calibration intervals of given characteristic length.

Parameters

runs	A map with key containing expNum+runNum and value start+end time in hours of the run
evts	A vector with all events
lossFunctionOuter	A formula of the outer loss function (for calib. intervals)
lossFunctionInner	A formula of the inner loss function (for calib. subintervals)
atomSize	lenght of the small calibration interval - atom (in hours)

Returns: : Vector of the calib. intervals always containing vector of calib. subintervals. Each subinterval is defined as a map spanning in general over several runs

Definition at line 163 of file Splitter.h.

◆ getStartEnd()

static std::pair<double, double> getStartEnd ( std::vector< std::map< ExpRun, std::pair< double, double >>> res )

inlinestatic

Get the start/end time of the calibration interval (vector of the calib.

subintervals).

Parameters

res	A single calibration interval (for example from getIntervals function)

Returns: : A pair with start/end time of the whole calib. interval
