Deformation analysis between epoch 1+2+..k-1 vs epoch k

Therefore, when designing the network in JAG3D, "A" is equal or smaller than 2.2mm, is that right?

The major-axis A depends on your selected α (and on the adjustment scheme of α to avoid multiple comparisons problem, i.e Baarda's B-method). The used α is given in the test-statistic table of JAG3D.

What are uncertainty of angle and distance input to JAG3D?

24 observations to the same point, observed from the same stand point???

If we observe several sets, we average the sets and use the manufacturer's specifications to define the a-priori uncertainties. After the adjustment process, the uncertainties are evaluated by variance-component-estimations and, if necessary, adjusted.

kind regards
