# ntpq -p

    space reject
        The peer is discarded as unreachable, synchronized to this server (synch loop) or outrageous synchronization distance.

    x  falsetick
        The peer is discarded by the intersection algorithm as a falseticker.

    .  excess
        The peer is discarded as not among the first ten peers sorted by synchronization distance and so is probably a poor candidate for further consideration.

    -  outlyer
        The peer is discarded by the clustering algorithm as an outlyer.

    +  candidat
        The peer is a survivor and a candidate for the combining algorithm.

    #  selected
        The peer is a survivor, but not among the first six peers sorted by synchronization distance. If the assocation is ephemeral, it may be demobilized to conserve resources.

    *  sys.peer
        The peer has been declared the system peer and lends its variables to the system variables.

    o  pps.peer
        The peer has been declared the system peer and lends its variables to thesystem variables. However, the actual system synchronization is derived from a pulse-per-second (PPS) signal, either indirectly via the PPS reference clock driver or directly via kernel interface.
