Function Documentation

◆ LALComputeMeanPower()

void LALComputeMeanPower	(	LALStatus *	status,
		REAL8 *	mean,
		REAL8Periodogram1 *	peri
	)

to compute mean power from a periodogram – obsolete – use LAL functions in NormalizeSFTRngMed.c

Parameters

status	pointer to LALStatus structure
mean	mean power
peri	periodogram

Definition at line 56 of file PeakSelect.c.

◆ LALSelectPeakWhiteNoise()

void LALSelectPeakWhiteNoise	(	LALStatus *	status,
		UCHARPeakGram *	pg,
		REAL8 *	thr,
		REAL8Periodogram1 *	peri
	)

select peakgram in white noise – obsolete – use LAL functions in NormalizeSFTRngMed.c

Definition at line 97 of file PeakSelect.c.

◆ LALUCHAR2HOUGHPeak()

void LALUCHAR2HOUGHPeak	(	LALStatus *	status,
		HOUGHPeakGram *	pgOut,
		UCHARPeakGram *	pgIn
	)

Compress explicit peak gram.

Parameters

status	pointer to LALStatus structure
pgOut	compressed peakgram
pgIn	explicit peakgram – collection of 1s and 0s

Definition at line 160 of file PeakSelect.c.

◆ LALPeriodo2PSDrng()

void LALPeriodo2PSDrng	(	LALStatus *	status,
		REAL8Periodogram1 *	psd,
		REAL8Periodogram1 *	peri,
		INT4 *	blocksRNG
	)

Wrapper for LALRunningMedian code – obsolete – use LAL functions in NormalizeSFTRngMed.c.

Parameters

status	pointer to LALStatus structure
psd	output psd
peri	input periodogram
blocksRNG	running median block size

Definition at line 215 of file PeakSelect.c.

◆ LALSelectPeakColorNoise()

void LALSelectPeakColorNoise	(	LALStatus *	status,
		UCHARPeakGram *	pg,
		REAL8 *	thr,
		REAL8PeriodoPSD *	in
	)

Function for selecting peaks in colored noise – obsolete – use LAL functions in NormalizeSFTRngMed.c.

Parameters

status	pointer to LALStatus structure
pg	output peakgram
thr	threshold reltive to psd
in	input psd and periodogram

Definition at line 286 of file PeakSelect.c.

◆ SFTtoUCHARPeakGram()

void SFTtoUCHARPeakGram	(	LALStatus *	status,
		UCHARPeakGram *	pg,
		const SFTtype *	sft,
		REAL8	thr
	)

Convert a normalized sft into a peakgram by selecting bins in which power exceeds a threshold.

Constructs peakgram from a normalized SFT – uses standard pulsar data types.

Parameters

status	pointer to LALStatus structure
pg	output peakgram
sft	standard pulsar sft type
thr	sft power threshold for peak selection
