Hello,

Thanks, but I cant open annotated link to see detailed explanation.

I've corrected the link to the paper called "Maximum Tolerable Biases (MTBs) and hardly detectable points in least-squares adjustment".

Hello Zaklina,

I only have one more question. What is ∇(1)″ in report? I mean, what math formula is implemented in software to get this value?

In JAG3D, the Maximum Tolerable Bias (MTB) denoted by ∇(1) is a further metric to analyse the reliability of the observations in a geodetic network, cf. 10.1080/00396265.2021.1924003

All the best
Micha

Thanks for all informations, I did project successfully.

Hello Zaklina,

I have 42 rows.
Problem is that I did not got all relative ellipses.
For most directions, these is missing relative confidence info.

You can not specify one point twice. For example, if you have specified S1 - S2, S1 - S3 will be ignored. Please note that the procedure is part of a deformation analysis and it is not usually useful to check whether the point S1 is congruent to S2 AND S3. So, you have to restrict the point nexuses.
