Sky distribution of sightlines in our COS sample in a Hammer-Aitoff projection of Galactic coordinates. Secure detections of high-velocity gas at | vLSR | = 100–500 km s-1 are indicated with filled circles, while tentative detections are labeled with crossed filled circles; open circles mark the non-detections. The mean absorption velocities of the dominant absorption components along each sightline are color-coded according to the color scheme at the bottom of the figure.
