Extended Data Fig. 8: Comparison of the appearance of reflex motion versus rotation.
From: Detection of the Milky Way reflex motion due to the Large Magellanic Cloud infall
a–c, Our reflex motion model, projected onto the (ℓ, b) plane in vlos, vℓ, vb. Velocities in each panel have been normalized to units of vtravel. d–f, A rotation model, with magnitude vϕ, projected onto the (ℓ, b) plane in vlos, vℓ, vb where velocities in each panel have been normalized to units of vrotation. The smoothed SEGUE footprint is outlined in black. Comparing the upper and lower rows shows that the line-of-sight and b velocities are similar, supporting the need for 6-dimensional data and all-sky coverage.
