Fig. 5


Absorption fraction (detection rate) of the transitions of Si iiiλ1206.5 (red), Si iiλ1260.4 (blue), Si iiλ1193.3 (green), and C ivλ1548.2 (orange) as a function of LSR velocity. C ii λ1334.5 is not included because of severe blending with C iiλ1335.7 at positive velocities. The gap near −250 km s-1 for Si iiλ1260.4 is due to blending with Galactic S iiλ1259.5.
