O VII He-like triplet in the observed frame of NGC 7469, with the three emission lines labelled in black (resonance, intercombination and forbidden for r, i and f, respectively). The spectrum (black crosses) is over imposed with the best fit model (red line). Two narrow components (EM1 and EM2) are shown by the blue and green lines, respectively, and a broad component (EM3) is plotted with the purple line. EM1 fits the forbidden line, EM2 fits the resonance line, as well as the forbidden line, and EM3 produces emission at location of the intercombination line, which is actually a broadened forbidden line with a large blueshifted velocity (as labelled with the purple “f”).
