The scripts in this directory are mainly used to display the nnn.dat
files that are logged when the "log_format" parameter is set.  See
comments at the beginnig of the scripts about what the arguments are.
These scripts have arguments, so should be run with the "call" gnuplot
command, like:
    call "gplt/dyn.gplt" "log/42.dat"

dyn.gplt
    Display various track state aspects v.s. time, speed,
    accelleration, turn rate, moving test criteria, etc.  This is good
    for getting a general sense of the behavior of a track.  Once you
    know a particular time that something interesting is happening,
    you can use show.gplt to show the raw data and tracked feature
    positions.  

dyn2.gplt
    Same as dyn.gplt, but for two tracks at once, for comparing
    performance with different parameter settings.

dyn_motion.gplt
    A subset of the info in dyn.gplt, used for published figure.

scans.gplt
scans2.gplt
    These are used to look at scan_log.dat to see general tracker real-time,
    iteration times, dropped scans, etc.

show.gplt
show2.gplt
    These show the measured and tracked feature positions and raw data points,
    useful for seeing more precisely what happens.

valid.gplt
    This displays validate.dat, which is a snapshot of the results driving
    history-based track validation taken at a particular time,
    specified by validate_trace_time, validate_trace_track.
