combinatoric_lnprior

ssapy.correlate_tracks.combinatoric_lnprior(nsat, ntrack, ndet)

Prior probability of assigning detections to tracks of satellites.

This function intends to give the prior probability that ndet detections of nsat total satellites correspond to ntrack satellites.

Parameters:

• nsat (int) – number of satellites that could possibly be observed

• ntrack (int) – number of tracks in current solution

• ndet (int) – number of detections of these satellites
