Notes. (a) The known SNR and molecular cloud associations are denoted by “a”. (b)The method for obtaining the RC ridge in CMDs: a kernel density estimation (KDE) or a normal parameter estimation (Normal). (c) Primary distance marked as “P”. (d) Secondary distance marked as “S”. (e) The radio-surface-brightness distances drad are from Pavlović et al. (2013). (f)The known distances dother are mainly kinematic distances from Green (2019b), where the symbol † describes the distance implied by the associated molecular clouds and X-ray observations, the symbol + describes the distance suggested by various observations. The symbol * denotes distances summarized in Stafford et al. (2019). The symbols ∧, ∨, ◃, △ denote distances from Hewitt & Yusef-Zadeh (2009), Slane et al. (1999), Vukotić et al. (2019), Suzuki et al. (2020), respectively.
