Lines (1)--(3) are combined fits to EPIC-pn and EPIC-MOS spectra in the energy interval $0.2{-}1.5$~keV. Lines~(4) and~(5) represent combined fits to EPIC and RGS using the same models
as in lines~(1) and~(2). Line~(6) lists the finally accepted two-component blackbody fit to the RGS-data alone with a fixed ratio of normalization parameters.
