◆ 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.
