  The Characterizing Exoplanets Satellite (CHEOPS) mission is planned for
launch next year with a major objective being to search for transits of known
RV planets, particularly those orbiting bright stars. Since the radial velocity
method is only sensitive to planetary mass, the radii, transit depths and
transit signal-to-noise values of each RV planet are, a-priori, unknown. Using
an empirically calibrated probabilistic mass-radius relation, forecaster (Chen
& Kipping 2017a), we address this by predicting a catalog of homogeneous
credible intervals for these three keys terms for 468 planets discovered via
radial velocities. Of these, we find that the vast majority should be
detectable with CHEOPS, including terrestrial bodies, if they have the correct
geometric alignment. In particular, we predict that 22 mini-Neptunes and 82
Neptune-sized planets would be suitable for detection and that more than 80% of
these will have apparent magnitude of V < 10, making them highly suitable for
follow-up characterization work. Our work aims to assist the CHEOPS team in
scheduling efforts and highlights the great value of quantifiable,
statistically robust estimates for upcoming exoplanetary missions.
