Prototypes
void	LALHOUGHInitializeHD (LALStatus *status, HOUGHMapDeriv *hd)
	This function initializes the Hough map derivative space HOUGHMapDeriv *hd to zero. More...
void	LALHOUGHAddPHMD2HD (LALStatus *status, HOUGHMapDeriv *hd, HOUGHphmd *phmd)
	Given an initial Hough map derivative HOUGHMapDeriv *hd and a representation of a phmd HOUGHphmd *phmd, the function LALHOUGHAddPHMD2HD() accumulates the partial Hough map derivative *phmd to *hd by adding +1 or -1 to the pixels corresponding to the left or right borders respectively. More...
void	LALHOUGHAddPHMD2HD_W (LALStatus *status, HOUGHMapDeriv *hd, HOUGHphmd *phmd)
	Adds a hough map derivative into a total hough map derivative taking into account the weight of the partial hough map. More...
void	LALHOUGHIntegrHD2HT (LALStatus *status, HOUGHMapTotal *ht, HOUGHMapDeriv *hd)
	This function constructs a total Hough map HOUGHMapTotal *ht from its derivative HOUGHMapDeriv *hd by integrating each row (x-direction). More...
void	LALHOUGHInitializeHT (LALStatus *status, HOUGHMapTotal *ht, HOUGHPatchGrid *patch)
	This function initializes the total Hough map HOUGHMapTotal *ht to zero and checks consistency between the number of physical pixels in the map and those given by the grid information structure HOUGHPatchGrid *patch. More...
void	LALStereo2SkyLocation (LALStatus *status, REAL8UnitPolarCoor *sourceLocation, UINT2 xPos, UINT2 yPos, HOUGHPatchGrid *patch, HOUGHDemodPar *parDem)
	Find source sky location given stereographic coordinates indexes. More...
