Distance of the dust layers along the line of sight of observed cluster directions inferred from visual inspection (light red squares) and BISP-1 algorithm (black points). The thick black line around the black point corresponds to the 16th and 84th percentiles of the cloud distance, and the thin line represents the 2.5 and 97.5 percentile ranges. The cluster distances are marked by different colored symbols at their respective Galactic latitude positions. The vertical lines represent the location of the Spiral arms: the Local arm (cyan), the Perseus arm (yellow), and the Outer arm (red).
