Notes. Column (1): source name; Columns (2) and (3): Equatorial coordinates; Column (4): Local Standard of Rest velocity; Column (5): the spiral arm, GC, Con, 3kN/F, Nor, ScN/F, SgN/F, Loc, Per, Out, OSC, LoS, and AqS indicate Galactic center region, connecting arm, 3 kpc arm (near/far), Norma arm, Scutum-Centaurus arm (near/far), Sagittarius arm (near/far), Local arm, Perseus arm, Outer arm, Outer-Scutum-Centaurus arm, Local arm spur, and Aquarius spur, respectively. See details in Reid et al. (2019); Column (6): the heliocentric distance, derived with parallaxes from the BeSSeL Survey (Reid et al. 2019); Column (7): galactocentric distance following equation (1). (*)For those 12 sources without parallax data and an asterisk in column 1, kinematic distances were estimated (see details in Section 2.1).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
