I is for ``ideal'' target selection, and N-I is for ``non-ideal'' target selection. Detectable transits are transits producing a signal-to-noise ratio greater than the threshold, confirmable transits are planets whose radial velocity motion can be detected, and detected transits correspond to detectable transit that can be confirmed by radial velocity follow-up, and with a period lower than $DT/2$.
