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
