Magnetic and non-magnetic CVs in the L_X − P_orb and the L_X − D planes. Luminosities, periods and distances were taken from Pretorius & Knigge (2012), Pretorius et al. (2013), Reis et al. (2013), Byckling et al. (2010), and Baskill et al. (2005). Luminosities given in certain spectral bands were corrected with bolometric correction factors using the spectral parameters given in the papers mentioned. The black larger symbol indicates the XMM-Newton observation of V405 Peg, whereas the bars crossing it indicate the range of luminosities as observed with Swift. Diagonal lines in the right panel indicate the survey limits of the RBS and with eROSITA.
