Function Documentation

float GRBP_probSpatialCalculate (  const GRBP_probSpatialCtl *  ctl, float  distance )

Returns the log, base 10, of the spatial probability for the angular distance distance. Returns: The log, base 10, of the spatial probability. Parameters: ctl  The control handle for calculating the spatial probability. distance  The angular separation expressed as 1 - dot_product.

const GRBP_probSpatialCtl * GRBP_probSpatialConstruct (  double  log10_costhetamax  )

Constructs the control structure use to when computing the spatial probability. Returns: Pointer to the control structure Parameters: log10_costhetamax  The log, base 10, of the cosine of the maximum opening angle, in radians. The maximum opening angle is the acceptance and is generally the equivalent of about ~115 degrees.

float GRBP_probTemporalCalculate (  const GRBP_probTemporalCtl *  ctl, float  delta_time )

Returns the log, base 10, of the temporal probability for the specified time difference delta_time. Returns: The log, base 10, of the spatial probability Parameters: ctl  The control handle for calculating the temporal probability delta_time  The time difference
