To date, a handful of exoplanets have been photometrically mapped using phase-modulated reflection or emission from their surfaces, but the small amplitudes of such signals have limited previous maps almost exclusively to coarse dipolar features on hot giant planets.

Here we propose a data-driven method to simultaneously extract precise RVs and infer the underlying stellar and telluric spectra using a linear model (in the log of flux).

We find weak gradients in all actions with stellar age, of (7. 51 +/- 0. 52, -29. 0 +/- 1. 83, 1. 54 +/- 0. 18) kpc km/s/Gyr for J_r, L_z, and J_z, respectively.
