Segment: 0 No-of-obs-used: 382
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 8.8 1.0 1.59 0.60 -2.9
E: -10.6 1.1 1.27 0.37 16.3
U: -9.3 1.7 5.71 0.61 1.2
Error bars are plus/minus one standard deviation
Error bars on individual observations = formal-error x scale-factor.
Currently the scale-factors are: N:3.0, E:4.0, U:3.0

Red points are positions determined using final orbits
Blue points are positions determined using preliminary orbits
Vel-stddev = sqrt(WN**2+RW**2)
where WN is a white noise contribution from propagating the error bars on the observations
and RW is a random walk contribution (= a*sqrt(timespan)/timespan where a is 0.001 m/yr**1/2)
