Function Documentation

unsigned char* GRBP_gammaListConstruct (  GRBP_gammaList *  list, const GRBP_DB_gammaList *  cfg, unsigned char *  ptr )

Constructs the gamma list. Returns: Pointer to the next available memory location Parameters: list  The list to construct cfg  The configuration of the gamma list ptr  The memory to carve the list from

int GRBP_gammaListMerge (  GRBP_gammaList *  list, unsigned short int  nrange, const GRBP_cluster *  clusters, signed short int  min_idx, unsigned short int  max, const unsigned int *  masks, unsigned short int  nmasks )

Fills the list of photons used to localization using the parent photon from the specified list of clusters. printf (" Photon #: %3u:%3u ", which, jp); printf ("ListCur:Cnt %4u:4u", listCur, listCnt);

void GRBP_gammaListReset (  GRBP_gammaList *  list  )

Resets the gamma list to an empty list. Parameters: list  The gamma list to reset

int GRBP_gammaListSeed (  GRBP_gammaList *  list, GRBP_probabilityLogs *  plog, float  dx0, float  dy0, float  dz0, float  distance_cut, const GRBP_probabilityPrms *  prob, const GRBP_photon *  photon, int  cnt )

Populates a gamma list with all the photons in the specified range that are within the distance_cut of the the GRB location. Returns: The number of photons entered Parameters: list  The list to populate. plog  Filled in with logs of the spatial and temporal probabilities dx0  The normalized X direction cosine of the seed location dy0  The normalized Y direction cosine of the seed location dz0  The normalized Z direction cosine of the seed location distance_cut  The distance cut to use. Only photons with 1 - cos (theta) are admitted to the list, where cos (theta) is the dot product of the photon's direction with the GRB location. prob  The parameters used in determining the spatial and temperal probabilities. photon  The first photon in the linked list to use cnt  The number of photons to use

int GRBP_gammaListSizeof (  const GRBP_DB_gammaList *  cfg  )

Computes the number of bytes needed for a gamma list of the specified configuration. Returns: The number of bytes needed for a gamma list of cfg elements Parameters: cfg  The configuration of the gamma list

static __inline GRBP_gamma * insert (  GRBP_gammaAux *  aux, GRBP_gamma *  gammas, int  cur, int  max, double  time )  [static]

Locates the insertion point and makes room for a gamma with the specified time. Returns: The insert point Parameters: aux  The auxilliary data of the gammas to scan gammas  The list of gammas to scan cur  The next available slot. This implies that the latest arriving photon is logically one slot earlier. max  The maximum number of photons in photons, i.e. the size of the circular list of photons time  The time of the photon to insert The list of gammas is scanned backwards in time order, looking for the first gamma with a time less than time. The information for each gamma failing this test is moved up a slot, thus creating an empty slot for either the new photon to be inserted or the next gamma in the list to be moved up.
