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
