Angular parameters

Rotation axis is given in polar angles (deg).
90.0,  90.0,        0.0,  0.0
0.0,   90.0,        2.0
Axis for rotation angle = 0 deg is given in polar angles (deg).
Start angle, End angle (deg)
Angle step (deg)

The angular parameters specify how you calculate the angular map of resonant positions. The Green values can be varied in user simulations. The author's values are used as the default in the simulations. We kindly recommend you to insert your experimental values into the Green part. This will be convenient, because the simulated result with the default values, will exactly correspond to your experimental data, which is helpful for the debug of your parameter file.

These values should be separated by comma “,” or space(s).

Angle step should be 2 deg or larger (not changed in user simulations). Because of the program's limit, the maximum number of data points in a simulation should be smaller than 2000 points. So, we do not set so fine Angle step (e.g., 0.5 deg).
