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

ZHRmax = 79 based on 4478 Orionids in 408 data intervals, assuming fixed population index r = 2.0 and zenith correction 1/sin(hR).
