Detailed Description

Class to correct channels for walk in the onboard filters.

The purpose of the WalkCorrector class is to correct certain channels for the walk (connected with the detector response, usually the lower the event energy, the slower is the response). The resulting correction should be subtracted from the raw time in order to compensate the slower response.

§ AddChannel()

void WalkCorrector::AddChannel	(	const Identifier &	chanID,
		const std::string &	model,
		const double &	min,
		const double &	max,
		const std::vector< double > &	par
	)

Add new channel, identified by chanID to the list of known channels and their calibration model, range and parameters

Parameters

[in]	chanID	: The ID to add to the known list of corrections
[in]	model	: the model to use to correct the channel
[in]	min	: The lower bound of the correction range
[in]	max	: The upper bound of the correction range
[in]	par	: The vector of parameters to use for the calibration

Definition at line 13 of file WalkCorrector.cpp.

Here is the caller graph for this function:

§ GetCorrection()

double WalkCorrector::GetCorrection	(	Identifier &	chanID,
		double	raw
	)		const

Returns time correction that should be subtracted from the raw time. The channel is identified by Identifier class, the correction is return accordingly to the selected model and parameters for the particular channel. If channel has not been added to the list, it returns 0 as a default value.

Parameters

[in]	chanID	: The channel identifier to get
[in]	raw	: The raw value to perform the correction on

Returns: The walk corrected value of raw

Here is the caller graph for this function:

§ Model_A()

double WalkCorrector::Model_A	(	const std::vector< double > &	par,
		const double &	raw
	)		const

protected

This model describes the correction as a function of raw energy (ch number): f(x) = a0 + a1 / (a2 + x) + a3 * exp(-x / a4) the returned value is in 'natural' pixie units Developed for 85,86Ga experiment

Parameters

[in]	par	: the vector of parameters for calibration
[in]	raw	: the raw value to calibrate

Returns: The corrected time in pixie units

Definition at line 161 of file WalkCorrector.cpp.

§ Model_B1()

double WalkCorrector::Model_B1	(	const std::vector< double > &	par,
		double	raw
	)		const

protected

This model was developed for the 93Br experiment f(x) = a0 + a1 * x + a2 * x^2 + a3 * x^3 + a4 / (1 + exp((x - a5) / a6)) the returned value is in 'natural' pixie units

This function is intended for low energy part, for high energy part use B2 model.

Parameters

[in]	par	: the vector of parameters for calibration
[in]	raw	: the raw value to calibrate

Returns: the corrected time in pixie units

Definition at line 168 of file WalkCorrector.cpp.

§ Model_B2()

double WalkCorrector::Model_B2	(	const std::vector< double > &	par,
		double	raw
	)		const

protected

This function is the second part of 'B' model developed for the 93Br experiment f(x) = a0 + a1 * x + (a2 + a3 * x + a4 * x^2) * exp(-x / a5) the returned value is in 'natural' pixie units

This function is intended for high energy part, for low energy part use B1 model.

Parameters

[in]	par	: the vector of parameters for calibration
[in]	raw	: the raw value to calibrate

Returns: corrected time in pixie units

Definition at line 175 of file WalkCorrector.cpp.

§ Model_None()

double WalkCorrector::Model_None ( ) const

protected

Returns: always 0. Use if you want to switch off the correction. Also not adding the channel to the list results in returning 0 from GetCorrection function.

Definition at line 157 of file WalkCorrector.cpp.

double WalkCorrector::Model_VB	(	const std::vector< double > &	par,
		double	raw
	)		const

protected

Parameters

[in]	par	: the vector of parameters for calibration
[in]	raw	: the raw value to calibrate

Returns: corrected time in ns

Definition at line 191 of file WalkCorrector.cpp.

§ Model_VD()

double WalkCorrector::Model_VD	(	const std::vector< double > &	par,
		double	raw
	)		const

protected

The correction for Small VANDLE bars in RevD the returned value is in ns

Parameters

[in]	par	: the vector of parameters for calibration
[in]	raw	: the raw value to calibrate

Returns: corrected time in ns

Definition at line 196 of file WalkCorrector.cpp.

§ Model_VL()

double WalkCorrector::Model_VL	(	const std::vector< double > &	par,
		double	raw
	)		const

protected
