Notes. We report, for each flash episode, the mass of the WD at the beginning of the cycle (MWD in M), the orbital period at the subsequent onset of mass accretion (Per., in minute), the mass accreted between two successive flashes (ΔMacc in 10−2 M), the mass of the He-rich zone with X(4He) > 0.1 ( Δ M He pk $ \Delta M_{\mathrm{He}}^{\mathrm{pk}} $ in 10−2 M), the mass lost during the flash-driven RLOF (ΔMlost in 10−2 M), the ignition density for He burning (ρHe in 105 g cm−3), the maximum temperature ( T He max $ T_{\mathrm{He}}^{max} $ in 108 K) and maximum luminosity ( L He max $ L_{\mathrm{He}}^{max} $ in 1010 L) attained during the He-flash, and the retention efficiency defined as η = 1 Δ M lost Δ M acc $ \eta=1-\frac{\Delta M_{\mathrm{lost}}}{\Delta M_{\mathrm{acc}}} $.
