I had only a 8 degr elevation pass and used both TLE for analyzing the doppler frequency.
Well, it seems my assumption was right – seems we have to change the TLE for PRISM to OBJECT J.
It was a pretty low pass and the deviation is not so high – but will analyze the next, higher pass tonight.

After this second pass with higher elevation (32 degr) I am sure that PRISM is OBJECT J.
