void	LALHOUGHupdateSpacePHMDdn (LALStatus status, PHMDVectorSequence phmdVS, HOUGHPeakGramVector pgV, HOUGHptfLUTVector lutV)
	Function for shifting the cylindrical buffer of PHMDs down by one frequency bin – the highest frequency bin is dropped and an extra frequency bin is added at the lowest frequency. More...

void	LALHOUGHConstructHMT (LALStatus status, HOUGHMapTotal ht, UINT8FrequencyIndexVector freqInd, PHMDVectorSequence phmdVS)
	Given PHMDVectorSequence phmdVS, the space of `phmd`, and UINT8FrequencyIndexVector freqInd, a structure containing the frequency indices of the `phmd` at different time stamps that have to be combined to form a Hough map, the function LALHOUGHConstructHMT() produces the total Hough map. More...

void	LALHOUGHComputeFBinMap (LALStatus status, UINT8 fBinMap, UINT8 f0Bin, HOUGHResidualSpinPar rs)
	This function computes the corresponding frequency bin of a `phmd` `UINT8 fBinMap` for a given intrinsic frequency bin of a source `UINT8 f0Bin`, and information regarding the time and the residual spin down parameters HOUGHResidualSpinPar *rs. More...

void	LALHOUGHConstructHMT_W (LALStatus status, HOUGHMapTotal ht, UINT8FrequencyIndexVector freqInd, PHMDVectorSequence phmdVS)
	Calculates the total hough map for a given trajectory in the time-frequency plane and a set of partial hough map derivatives allowing each PHMD to have a different weight factor to account for varying sensitivity at different sky-locations. More...

void	LALHOUGHWeighSpacePHMD (LALStatus status, PHMDVectorSequence phmdVS, REAL8Vector *weightV)
	Adds weight factors for set of partial hough map derivatives – the weights must be calculated outside this function. More...

void	LALHOUGHComputeAMWeights (LALStatus status, REAL8Vector weightV, LIGOTimeGPSVector timeV, LALDetector detector, EphemerisData *edat, REAL8 alpha, REAL8 delta)
	Computes weight factors arising from amplitude modulation – it multiplies an existing weight vector. More...

void	LALHOUGHComputeMultiIFOAMWeights (LALStatus status, REAL8Vector weightV, SFTCatalog catalog, EphemerisData edat, REAL8 alpha, REAL8 delta)
