bool	m_isValid
	Data stored in this TTD info object is actually valid.

bool	m_isHER
	Injection is in HER/LER.

bool	m_revo2
	Lowest bit of revolution counter (PXD needs ~2 revolutions to readout one frame)

unsigned int	m_timeSinceLastInjection
	Time since the last injection in clock ticks (127MHz=RF/4 clock) Note: A value of 0x7FFFFFFF (see `c_flagNoInjection`) means no injection took place recently (value is defined by the RawFTSW) Note: This is actually the time since the injection-pre-kick signal was received so there is some offset (different for HER/LER) that will be handled by the analysis variable.

unsigned int	m_timeSincePrevTrigger
	Time since the previous trigger in clock ticks (127MHz=RF/4 clock)

unsigned int	m_bunchNumber
	Number of triggered bunch, ranging from 0-1279 (in 127MHz clock ticks) Note: There are a maximum of 5120 buckets, which could each carry one bunch of e+/e-, but we only have 1280 clock ticks (=5120/4) to identify the bunches Note: This is the bunch number as given by the TTD. More...

Static Private Attributes
static const unsigned int	c_flagNoInjection = 0x7FFFFFFF
	This number is defined by the FTSW to indicate no injection happened recently.

Detailed Description

Member Data Documentation

◆ m_bunchNumber

unsigned int m_bunchNumber

private

Number of triggered bunch, ranging from 0-1279 (in 127MHz clock ticks) Note: There are a maximum of 5120 buckets, which could each carry one bunch of e+/e-, but we only have 1280 clock ticks (=5120/4) to identify the bunches Note: This is the bunch number as given by the TTD.

This might not be the 'global' bunch number, but the offset is taken into account by the method getTriggeredBunchNumberGlobal().
