CoordTrans - 2 local system

Hi Marko,

I have sent you my data,

I now had the time to take a look at the coordinates. Everything looks fine from my point of view. If you reduce your coordinates manually, the shift will be small. However, it is still the identical transformation, i.e. the weighted sum of squared residuals is (almost) identical, i.e., 5.84452183E-4 (reduced systems) vs. 5.84452188E-4 (original data). I'm not sure about your expectations, but large shift values are not an indicator of a poor transformation.

Kind regards
Micha
