Normalized PCA components f_k(E) (left panels) of the XMM-Newton pn+MOS2 (top), Chandra ACIS-S X1 (middle), and X2 (bottom) of Haro 11, along with the corresponding time-binned light curves A_k(t) (right). The fractional percentage variability of each PCA component is also given in the left panel. The energies corresponding to the possible lines that arise from H-like and He-like ions are marked.
