Functions
static __inline int	convert (int val, const ECR_calLogEnd *cal)
	Converts ADC value into standard units (Log Energy Units). LEUs are the standard unit internally used by the filter code.

	Returns the size, in bytes, of a QSE_ecal structure.
void	QSE_ecalConstruct (QSE_ecal *ecal)
	Does the intial construction of an QSE_ecal structure.

Function Documentation

static __inline int convert	(	int	val,
		const ECR_calLogEnd *	cal
	)			[static]

Converts ADC value into standard units (Log Energy Units). LEUs are the standard unit internally used by the filter code.

Returns:

The energy, in LEUs.

Parameters:

	val	The ADC value to convert
	cal	The calibration values for one log end

A simple linear conversion is used and a scaling factor is applied to convert an ADC value to an energy in LEUs (at one time 1 LEU = 1/4 MEV).

static __inline int * fill_tower	(	QSE_ecalTwr *	etwr,
		QSE_ecalGbl *	egbl,
		int *	elogs,
		const QSE_calTwr *	twr,
		const ECR_calTower *	ctwr
	)			[static]

Prints an ASCII formatted dump of a CAL tower record.

Parameters:

	etwr	The QSE_ecalTwr structure to fill
	egbl	The QSE_ecal structure to update with total energies
	*elogs	The pointer to arrary of log energies to fill
	twr	The unpacked CAL data for the tower
	ctwr	The calibration constants for this tower

void QSE_ecalConstruct

(

QSE_ecal *

ecal

)

Does the intial construction of an QSE_ecal structure.

Parameters:

ecal

The QSE_ecal structure to construct

void QSE_ecalFill	(	QSE_ecal *	ecal,
		const QSE_cal *	cal,
		const ECR_cal *	clb,
		unsigned int	options
	)

Produces an ASCII display of the CAL data.

Parameters:

	ecal	The QSE_ecal structure to fill
	cal	A previously unpacked CAL LAT Record.
	clb	The CAL calibration constants
	options	An options mask. The top 16 bits are a mask of which towers to print (MSB = TOWER 0), the low bit indicates to print the summary

int QSE_ecalSizeof

(

void

)

Returns the size, in bytes, of a QSE_ecal structure.

Returns:

The size, in bytes, of a QSE_ecal structure
