Fig. 4

Prominent broad absorption features in the 2013 COS spectrum of NGC 985. We plot normalized relative fluxes as a function of velocity relative to the systemic redshift of z = 0.043. The spectra have been binned by 8 pixels (1 resolution element) for display purposes. The top panel shows the C iii* multiplet. The middle two panels show the Si iv and C iv absorption troughs with the red component of each doublet as a red line and the blue component as a blue line. The bottom panel shows the Lyα absorption trough. The smooth thin line in each panel shows our fit to the normalized spectrum.
