CoachThe occurrence rate of a class of planets is the mean number of such planets per star, or the fraction of stars that host one, in a given range of size (or mass) and period, after the counts of a survey are corrected for the planets it could not detect: those whose orbits are not aligned for a transit, and those too small or too far to be seen.
