€By
performing a Fourier Transform of the previous data, the main
periodicities can be identified
–orbital
period
–white
dwarf spin
–beat
(very faint in this system)
€Also
evident are harmonics when the variations are non-sinusoidal (2w, 3w,
2W)
€The
variation of X-rays at a higher frequency suggested that due to
magnetically controlled accretion – but with a lower field than Polars/AM Her
systems
