Segment: 0 No-of-obs-used: 10
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 13.0 0.6 2.61 0.76 16.3
E: 13.9 0.6 3.54 0.92 -0.7
U: 1.4 1.6 6.11 0.55 9.9
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
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)
