Development of the wavelength range 1180–1210 Å during the first three epochs (top to bottom: days 23, 105, and 173). The high velocity (–1330 km s^-1) narrow absorption component is indicated with a link to the rest wavelength (in most cases the interstellar contribution). Note that narrow displaced absorption was also detected for transitions that did not display interstellar components, i.e., those from excited fine structure states. See text for details.
