Set the parameters used to compute conjunction probability for nonlinear relative motion.
ACAT <AdvCatObjPath> Probability {Parameters}
The ACat Probability command is used to set the parameters used to compute conjunction probability for nonlinear relative motion.
Use the ACatEvents_RM and ACatProbability_R commands to compute conjunction probability.
The following table describes the Probability {Parameters}.
| {Parameters} | Description |
|---|---|
| Resolution <Value> | Specify the grid size for parallelipipeds. <Value> is entered in Connect distance units and must be greater than 1 micron. |
| MaxSigmaStep <Value> | Specify the maximum allowable length of cylinder axis in sigma space. <Value> must be greater than or equal to 0.1. |
| EndSigma <Value> | Computation will be skipped if cylinder axis end exceeds this value in sigma space. <Value> must be greater than or equal to 0.1. |
| FracProbLimit <Value> | Specify the acceptable difference between linear and nonlinear computations. The fractional probability limit <Value> must be >= 1.e-6 and <= 0.99 |
| IntegrationDuration <Value> | <Value> must be greater than or equal to 0.0. This value sets the time duration from TCA for integrating probability. If 0.0, then this will be set to 0.5 the period of the primary object's period at TCA. |
| MaxAnglularBend <Value> | Specify the maximum allowable angular difference between adjoining cylinders. <Value> is entered in degrees and must be >= 1.e-6 and <= 90.0 degrees |
| MaxTimeStep <Value> | Specify the maximum allowable time step between adjoining cylinders. <Value> is entered in Connect time units and must be greater than 0.001 secs. |
