Ca ii lines in 2005 (bottom: FEROS spectrum) and 2012 (top: X-shooter spectrum); a) the Ca ii H and K lines show very broad and deep absorption; b) the [Ca ii] λλ7291, 7324 lines are in emission; and c) the Ca ii near-infrared lines at λλ8498, 8542, 8662 Å are in absorption. The Paschen lines λλ8502, 8545, 8665 Å can be seen in absorption just to the right of the Ca ii triplet lines. (The continuum is normalized to unity.)
