Table 1: Log of the XMM-Newton RGS observations of Mkn 421 taken in 2002 and 2003 that were used during this analysis. A further observation of Mkn 421 0537_0136540701 was also performed during the cooling of RGS1 which we have not used. ^a Total amount of Good Time Intervals. ^b The reprocessing of these data failed; we exclude them from further analysis.

Table 7: $\lambda /\Delta \lambda _{\it FWHM}$ ratios for the possible astronomical features observed in the RGS-1 spectra of Mkn 421. The instrumental resolving power is $\lambda /\Delta \lambda _{\it FWHM} < 500$ .
Table A.1: Best-fit parameters of the RGS spectra reproduced with power-law, broken power-law and parabolic models. We fixed the absorption parameter to the Galactic value. The error bars refer to the 90% confidence interval. ^a erg cm^-2 s^-1.
Table A.2: Best-fit parameters of the ToO RGS and EPIC-PN spectra fitted with power-law and broken power-law models, in the common energy range ([0.6-1.77] keV). The absorption parameter was fixed to the Galactic value. Systematic errors of 3% and of 0.5% were added to the RGS and to the EPIC-PN data, respectively. The error bars refer to the 90% confidence interval for one parameter. ^a erg cm^-2 s^-1.
