Fig. 1


LSR velocities of the Norma (cyan), Scutum-Centaurus (green) and Sagittarius-Carina (red) spiral arms as function of galactic longitude, as estimated by Reid et al. (2014). The width of the lines, 8 km s-1, is equivalent to the spatial width of the filaments from (Reid et al. 2014). For simplicity, we only show the near kinetic distances of the spiral arms. Each line segment represents a GMF, taking the vLSR values from the ends of the filaments. The line segments ended with black circles show GMFs of our sample while those with white stars belong to R14. We also show Nessie, with a red line ended in red circles.
