Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 12.2 1.0 1.65 0.61 3.3
E: -7.1 1.0 1.58 0.40 20.8
U: -15.7 1.5 5.06 0.53 0.3
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)
