\caption{Measured positions and flux estimate or upper limits of the strongest lines in the~RGS spectra of HD~223460 obtained during revolutions~107 and~200. The columns give the predicted line positions, the measured line positions during revolution~107, the measured line positions during revolution~200, the ion and line identifications, the temperatures of maximum line formation, the line fluxes measured during revolution~107 and the line fluxes measured during revolution~200.\label{tab7}}
