Polars: modelling the
cyclotron radiation
The cyclotron radiation pattern (intensity and polarisations) has been calculated by several groups as a function of viewing angle, wavelength: various levels of sophistication
From this the total polarised emission from any surface element can be calculated
It is possible to iterate the map of emission points to gradually converge to the right map for the observed polarisations (Stokes Imaging, Potter, Hakala)
Produces a map of cyclotron emission
