Radial velocity curve for HD 102195b. The planet was observed during the nights of 9 (red), 17 (blue), and 26 (green) March 2016, covering three ranges of planetary orbital phases 0.46–0.50, 0.40–0.44, and 0.59–0.63. During these phase intervals, the planet orbital motion changes by tens of kilometres per second, while telluric and stellar contaminations are stationary signals in wavelength.
