Segment: 0 No-of-obs-used: 8
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 8.9 1.5 3.14 0.30 8.8
E: 9.1 1.3 9.00 1.00 -3.2
U: 6.1 1.5 8.19 0.77 10.6
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)
