Which coordinate system is indispensable when mapping the large-scale architecture of the Milky Way, such as measuring the rotation curve?
Answer
The Galactic Coordinate System (GCS)
The GCS is indispensable when studying the large-scale architecture of the Milky Way, including mapping dust lanes and determining the distribution of stellar populations across the galactic disk.
