Stand-off distances (d), pre-shock velocities (V_pre-shock), post-shock temperatures (T_post-shock) and cooling parameters (χ) calculated at the three orbital phases selected for the hydrodynamic simulations, respectively, for the primary (1) and the secondary (2) of the system. The velocities were calculated on the basis of the terminal velocities and radii provided in Table 3, using a β= 1.0 velocity law. We note that, as the estimate of the pre-shock velocities depends on the radius of the stars, the uncertainty on this latter quantity might be responsible for uncertainties on the calculated pre-shock velocities, and therefore on the post-shock temperatures as well.
