The novae included in Table 4, except RR Tel and partially GK Per, were observed in X-rays at quiescence because of accretion. However, only 11 out of 81 quiescent Galactic novae observed in the pointed observations were detected.

% The consequences are, e.g., secular mass erosion, spin-up due to angular momentum accretion, an inhomogeneous temperature distribution over the white dwarf surface, short-term heating and cooling of the white dwarf envelope in response to changes in the accretion rate, retarded core cooling compared to non-accreting...
