◆ getADCFromCharge()

long int getADCFromCharge	(	const Belle2::VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip,
		const double &	charge
	)		const

inline

Return a signed long integer corresponding to the ADC pulse height per strip, provided the charge [e] collected on that strip.

Input:

Parameters

sensorID	identity of the sensor for which the calibration is required
isU	sensor side, true for p side, false for n side
strip	strip number
charge	the charge in units [e] is also required as input argument

Output: an integer number representing the ADC pulse height for the correponding input charge, on the given strip. The output is capped at 255.

Definition at line 85 of file SVDPulseShapeCalibrations.h.

     {
       return roundl(charge * getGain(sensorID, isU, strip));
     }

◆ getCappedADCFromCharge()

unsigned char getCappedADCFromCharge	(	const Belle2::VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip,
		const double &	charge
	)		const

inline

Return an unsigned 8 bit integer corresponding to the ADC pulse height per strip, provided the charge [e] collected on that strip.

Input:

Parameters

sensorID	identity of the sensor for which the calibration is required
isU	sensor side, true for p side, false for n side
strip	strip number
charge	the charge in units [e] is also required as input argument

Output: an integer number representing the ADC pulse height for the correponding input charge, on the given strip. The output is capped at 255.

Definition at line 109 of file SVDPulseShapeCalibrations.h.

◆ getChargeFromADC()

double getChargeFromADC	(	const Belle2::VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip,
		const double &	pulseADC
	)		const

inline

Return the charge (number of electrons/holes) collected on a specific strip, given the number of ADC counts.

Input:

Parameters

sensorID	identity of the sensor for which the calibration is required
isU	sensor side, true for p side, false for n side
strip	strip number
pulseADC	: The ADC-pulse height, a double between 0 and 255 (included)

Output: float corresponding to the charge [e] converted from the read ADC pulse.

Definition at line 61 of file SVDPulseShapeCalibrations.h.

◆ getGain()

float getGain	(	const VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip
	)		const

inlineprivate

Return the channel gain.

the gain is expressed in ADC counts / # electrons injected in the channel That is: pulseADC / gain = charge [e] charge * gain = pulse height [ADC counts]

Definition at line 181 of file SVDPulseShapeCalibrations.h.

◆ getPeakTime()

float getPeakTime	(	const VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip
	)		const

inline

Return the peaking time of the strip.

Input:

Parameters

sensorID	identity of the sensor for which the calibration is required
isU	sensor side, true for p side, false for n side
strip	strip number
charge	the charge in electrons

Output: a float number corresponding to the peaking time

Definition at line 131 of file SVDPulseShapeCalibrations.h.

◆ getWidth()

float getWidth	(	const VxdID &	sensorID,
		const bool &	isU,
		const unsigned short &	strip
	)		const

inline

Return the width of the pulse shape for a given strip.

Since it is provided from local run measurements in [APV clock/8] units, the correct value to be uploaded on the central DB for the width in [ns], the conversion factor [31.44ns/8] must be applied. The payload already retrieves the converted width in [ns].

Input:

Parameters

sensorID	identity of the sensor for which the calibration is required
isU	sensor side, true for p side, false for n side
strip	strip number

Output: a float number corresponding to the pulse width in ns.
