Segment: 0 No-of-obs-used: 7
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 4.7 0.9 4.67 1.55 -5.1
E: -4.2 1.0 1.59 0.43 -0.5
U: 7.4 2.7 3.40 0.31 8.3
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)
