esti_timeShift()

double esti_timeShift

(

const KLMChannelIndex &

klmChannel

)

Estimate value of calibration constant for uncalibrated channels.

Parameters

[in]

klmChannel

KLM channel index.

Definition at line 1409 of file KLMTimeAlgorithm.cc.

execute()

EResult execute ( std::vector< Calibration::ExpRun >  runs = {}, int  iteration = 0, IntervalOfValidity  iov = IntervalOfValidity()  )

inherited

Runs calibration over vector of runs for a given iteration.

You can also specify the IoV to save the database payload as. By default the Algorithm will create an IoV from your requested ExpRuns, or from the overall ExpRuns of the input data if you haven't specified ExpRuns in this function.

No checks are performed to make sure that a IoV you specify matches the data you ran over, it simply labels the IoV to commit to the database later.

fillTimeDistanceProfiles()

void fillTimeDistanceProfiles ( TProfile *  profileRpcPhi, TProfile *  profileRpcZ, TProfile *  profileBKLMScintillatorPhi, TProfile *  profileBKLMScintillatorZ, TProfile *  profileEKLMScintillatorPlane1, TProfile *  profileEKLMScintillatorPlane2, bool  fill2dHistograms  )

private

Fill profiles of time versus distance.

Parameters

[out]	profileRpcPhi	BKLM RPC phi plane.
[out]	profileRpcZ	BKLM RPC z plane.
[out]	profileBKLMScintillatorPhi	BKLM scintillator phi plane.
[out]	profileBKLMScintillatorZ	BKLM scintillator z plane.
[out]	profileEKLMScintillatorPlane1	EKLM scintillator plane1.
[out]	profileEKLMScintillatorPlane2	EKLM scintillator plane2.
[in]	fill2dHistograms	Whether to fill 2d histograms.

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 algorihtm.

readCalibrationData()

CalibrationAlgorithm::EResult readCalibrationData ( )

private

Read calibration data.

Returns

CalibrationAlgorithm::c_OK if the amount of data is sufficient, CalibrationAlgorithm::c_NotEnoughData otherwise.

setInputFileNames() [1/2]

void setInputFileNames ( PyObject *  inputFileNames )

inherited

Set the input file names used for this algorithm from a Python list.

Set the input file names used for this algorithm and resolve the wildcards.

Definition at line 166 of file CalibrationAlgorithm.cc.

setInputFileNames() [2/2]

void setInputFileNames ( std::vector< std::string >  inputFileNames )

protectedinherited

Set the input file names used for this algorithm.

Set the input file names used for this algorithm and resolve the wildcards.

Definition at line 194 of file CalibrationAlgorithm.cc.

setLowerLimit()

void setLowerLimit ( int  counts )

inline

Set the lower number of hits collected on one sigle strip.

If the hit number is lower than the limit, the strip will not be calibrated and set the average value of the calibration constant.

Definition at line 160 of file KLMTimeAlgorithm.h.

    {
      m_lower_limit_counts = counts;
    }

setMC()

void setMC ( bool  mc )

inline

Set flag indicating whether the input is MC sample.

The histogram ranges are different for data and MC. This setting cannot be determined automatically, because the collector output does not contain metadata.

Definition at line 134 of file KLMTimeAlgorithm.h.

timeDistance2dFit()

void timeDistance2dFit ( const std::vector< std::pair< KLMChannelNumber, unsigned int > > &  channels, double &  delay, double &  delayError  )

private

Two-dimensional fit for individual channels.

Parameters

[in]	channels	Channels.
[out]	delay	Delay (ns / cm).
[out]	delayError	Delay error.

Definition at line 647 of file KLMTimeAlgorithm.cc.

tS_lowerStrip()

std::pair< int, double > tS_lowerStrip

(

const KLMChannelIndex &

klmChannel

)

Tracing avaiable channels with decreasing strip number.

Parameters

[in]

klmChannel

Definition at line 1466 of file KLMTimeAlgorithm.cc.

tS_upperStrip()

std::pair< int, double > tS_upperStrip

(

const KLMChannelIndex &

klmChannel

)

Tracing avaiable channels with increasing strip number.

Parameters

[in]

klmChannel

KLM channel index.
