Table 2: Characteristics of radio bright H II regions and supernova remnants in the vicinity of Wd 1. Column 1 contains a name based on the Galactic coordinates of the object. Columns 2 and 3 contain information about the systemic velocity and derived kinematic distance found in the literature (Russeil 2003). Column 4 contains the distance to the source based on the rotation curve and method described in Sects. 3.1 and 4.1, respectively. Column 5 indicates the proposed spiral arm the object resides in.
