Segment: 0 No-of-obs-used: 4
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 6.5 12.8 1.71 0.25 7.9
E: -2.8 9.5 1.64 0.33 4.9
U: -6.1 13.7 3.22 0.44 -1.1
Error bars are plus/minus one standard deviation
Error bars on individual observations = formal-error x scale-factor.
Currently the scale-factors are: N:, E:, U:
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)
