Yes, an example is "Local stellar kinematics from Hipparcos data" [0]. Afaict: stars have color (red or blue shift) which represents relative motion; Hipparcos is a large large dataset from an eponymous satellite; fancy math determines relative motion based on position and inferred distance. 0. https://arxiv.org/abs/astro-ph/9710077

You're right that I inadvertently mischaracterized Siegel's article. I expected him to quantify the Z-motion of the solar system in the remainder of the text, and would have known that he did not if I had not lazily and sloppily declined to read the remainder. I simply relied on his reputation as a science popularizer while looking for a popular treatment rather than parametric quantities. Turning to the latter, it is well known that the residual solar motion with respect to the average of local stars is U_sun ~ -10 km s^1, V_sun ~ 5-15 km s^-1, W_sun = 7 km s^-1, leading to the sun moving…
