For each estimation interval: time is the middle of the interval, nINT is the number of observing periods and nPER is the number of Perseids involved. ZHR = (1 + sum nPER) / 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.

Maximum profile

ZHRmax = 131 based on 21353 Perseids in 2399 data intervals, assuming fixed population index r = 2.1 and zenith correction 1/sin(hR).
