Caption: Figure 8.

The 1D velocity (left y-axes) and FWHM widths (right y-axes) of the Fe XXV (top panel) and O VIII/N VII (bottom panel) lines vs. the super-orbital phase. The right y-axis on the bottom panel only contains the FWHM width of the O VIII line. The observations with XMM-Newton during the 2020 campaign are shown in black, archival XMM-Newton observations are shown in blue, and Chandra observations are shown in red.
