Implication

Analysis reveals the inner rotation curve of the Milky Way, highlighting the role of the terminal velocity method and very long baseline interferometer.

Key Points

Inner rotation curve was derived using the terminal velocity method with high accuracy, revealing key galactic dynamics.
The comprehensive RC integrates various surveys and compares East–West asymmetry in velocity profiles.
This analysis of the Milky Way's rotation provides crucial insight into its bulge, disc, and dark halo components.
Findings may indicate the influence of a weak bar structure within the central region of the Milky Way.
