Distance PDFs for star-forming region G040.96+02.48. The term “kinematic” denotes the PDF derived solely from the LSR velocity. Abbreviations for the proper motions in Galactic longitude and latitude directions are Pml and Pmb, respectively. The black curve combines different components (colored curves) and yields a 3D kinematic distance of 20.2 ± 3.2 kpc.
