\caption {\label{tab:fit}Best-fitting models and X-ray fluxes at Earth for each \xmm\ observation of HD~191612. 
%The fitted model has the form {\tt wabs($N_{\rm int}^{\rm H}$)*[wabs($N^{\rm H}_1$)*mekal(k$T_1$)+wabs($N^{\rm H}_2$)*mekal(k$T_2$)]}, with {\tt wabs($N_{\rm int}^{\rm H}$)}$=3.4\times10^{21}$~cm$^{-2}$ \citep{dip94}. Quoted fluxes are in the 0.4$-$10.0~keV energy range, and the unabsorbed fluxes $f_{\rm X}^{\rm unabs}$ are corrected only for the interstellar absorbing column. For each parameter, the lower and upper limits of the 90\% confidence interval (derived from the {\sc error} command under XSPEC) are noted as indices and exponents, respectively. The normalisation factors are defined as $\frac{10^{-14}}{4\pi D^2} \int n_e n_{\rm H} dV$, where $D$, $n_e$ and $n_{\rm H}$ are respectively the distance to the source, the electron and proton density of the emitting plasma. The phases $\phi_{orb}$ and $\phi_{cyc}$ correspond to the phases in the orbital cycle and the 538~d line profile/photometric cycle, respectively (ephemeris of \citealt{how07}). The 2005 results are reproduced from \citet{naz07}.
