Contour plots (in black for obs. 1, and in red for obs. 2) of line flux versus line energy (source frame) for the narrow emission Gaussian line in Mrk 841. The three confidence levels are for 68, 90, and 99%, respectively. In grey, we superimpose the contour plots of 2001–2005 XMM/Newton observations (see P07, Fig. 9).
