Top panels: Eight Gaussian lines from the  ~1 keV complex detected by Suzaku, before (left panel) and after (right panel) the 2008 torque reversal. Here the dotted lines in the model denote the components that were fixed. The residuals after fitting only the continuum model are shown in the middle panel, with no line emission included. The bottom panel shows the residuals after fitting the line complex with those 8 lines (see Table 2 for more information about these lines).
