Cumulative histogram (with a bin size of 1 day) of the discovery rates over the 10 yr LSST lifetime for the single-component (blue), two-component (purple), and rolling power-law (orange) models. These are further split by (top row) L4 discoveries and (bottom row) L5 discoveries, with L5 discovery delayed until the cloud is observable in the survey. The points of 50% (open triangle), 80% (open square), and 90% (open circle) completion are shown for each model. Red dashed vertical lines represent survey year start/end points. The pronounced plateau in year 1 discoveries corresponds to an early surge of L4 detections, followed by a lull until sky rotation brings the L5 cloud into an observable airmass.
