IS absorption along lines of sight within 15 of Sco–Cen as probed by 3 Cen A (black), HD1095793 (blue), HD110058 (orange), and HD131488 (red). This figure shows Fe II λ2586 absorption in velocity space. Prominent absorption components are labeled: the velocities in blue are previously identified absorbers in nearby lines of sight, while the black lines are the average velocities from the four reference stars used in the Lyα reconstruction.
