For each estimation interval: time is the middle of the interval, nINT is the number of observing periods and nLEO is the number of Leonids involved. ZHR = (1 + sum nLEO) / sum(Teff/C) where Teff is the effective observing time and C is the total correction for limiting magnitude, clouds and zenith correction. The solar longitudes refer to equinox J2000.0.

Morning of 19 November

ZHRmax = 78 based on 1422 meteors in 416 data intervals, assuming fixed population index r = 2.5 and zenith correction 1/sin(hR).
