Parameters of the CD-30°11223 system plotted against the mass of the WD companion with contours marking the 1σ (red), 2σ (light blue), and 3σ (dark blue) levels of confidence. In the left column tidal synchronisation of the sdB primary is assumed, while in the middle column the effect of microlensing has also been taken into account. Instead, in the right column the WD mass-radius relation has been used as an additional constraint. The solid lines in the mass-radius plots (second panels from the top) mark the zero-temperature mass-radius relation for WDs, the dashed lines more realistic models with 5% inflation. Note that both the v_rotsini and the log g derived from the light curve are in agreement with the values derived from spectroscopy.
