  We present phase-resolved XMM_Newton data of three short period polars: V347
Pav, GG Leo and EU UMa. All three systems show one dominant accretion region
which is seen for approximately half of the orbital cycle. GG Leo shows a
strong dip feature in its X-ray and UV light curves which is due to absorption
of X-rays from the accretion site by the accretion stream. The emission in the
case of EU UMa is dominated by soft X-rays: its soft/hard X-ray ratio is
amongst the highest seen in these objects. In contrast, GG Leo and V347 Pav
shows a ratio consistent with that predicted by the standard shock model. We
infer the mass of the white dwarf and explore the affect of restricting the
energy range on the derived parameters.
