... During execution of attitude quality tests, the two tables of attitude coefficients were generated. This tables related to the same time interval on 18. 04. 1997, but have a different time resolution - 15 and 3 min. Using this tables, we have restored the magnetic field measurement. On this panels the measurement and the model(Tsyg96) magnetic field are plotted. 3 min resolution table turn out availiable to provide the better approach to the model magnetic field. ...
