Segment: 0 No-of-obs-used: 6
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: 4.7 2.7 3.62 0.40 5.4
E: 6.0 2.2 5.82 0.80 -2.7
U: 3.8 2.7 11.00 1.21 6.0
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)
