Kepler-62
13.75 is only the star's Kepler Magnitude and that is from a much wider wavelength range compared to the Johnson V magnitude. Actually, Borucki et al 2013 assumes the G band magnitude value as being roughly the same as the V band for the star, and gives that as 14.4. Quoting from Borucki et al 2013, where they're showing no stellar companion exists, "These show a root-mean-square (rms) uncertainty of about 3 m/s, consistent with the RV errors for a g-band magnitude (similar to V) of 14.4 mag."
