Function Documentation

ListOfRfValues() [1/2]

void UtilBeam::ListOfRfValues	(	int &	n_value,
		double *&	list_values
	)

Make a list of QIE RF+nn values.

This function uses an array of "double", instead of "int". It is suitable for the constructors of the TH1 classes.

int num_inte;
double* list_inte;
UtilBeam::ListOfRfValues(num_inte, list_inte);
TH1* h1_rf_inte = new TH1D("h1_rf_inte", "", num_inte - 1, list_inte);

ListOfRfValues() [2/2]

void UtilBeam::ListOfRfValues	(	int &	n_value,
		int *&	list_values
	)

Make a list of QIE RF+nn values.

The possible values for QIE RF+nn are not evenly distributed. This function just fills list_values with a list of all values. The values are taken from "float_2_linrom-2.xls" in DocDB 537.

PoTLive()

double UtilBeam::PoTLive

(

const unsigned int

spill_id

)

Return the live number of PoT.

The QIE pedestal is not subtracted at present.

PoTPerQIE()

double UtilBeam::PoTPerQIE

(

const unsigned int

spill_id

)

Return PoT/QIEsum.

The QIE pedestal is subtracted from QIEsum.

PoTRaw()

double UtilBeam::PoTRaw

(

const unsigned int

QIE2Proton()

double UtilBeam::QIE2Proton	(	const int	qie_count,
		const unsigned int	spill_id
	)

Convert the QIE count to the number of protons.

This function does not subtract the QIE pedestal from qie_count.
