3. Python version is

I have the same problem with another file from the same dataset.

Looking at the code and the observation files I guess the problem comes form "Nsvsys = 36" line 94 of obs2.py, becausesome satellites have a higher number than 36. Could it be possible to increase it perhaps?

Thank you very much for these detailed reports!
