We confirm the planetary nature of the companion via a combination of radial velocities, which limit the mass to $< 4. 1\,\mathrm{M_J}$ $(3\sigma)$, and a clear Doppler tomography signal, which indicates a retrograde projected spin-orbit misalignment of $\lambda = -179. 7^{+3. 7}_{-3. 8}$ degrees.

We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measurements from FIES@NOT, HARPS-N@TNG, and the coud\'e spectrograph on the McDonald Observatory 2. 7 m telescope.
