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

Outburst profile

ZHRmax = 167 based on 158 Alpha-Aurigids in 53 data intervals, assuming fixed population index r = 2.0 and zenith correction 1/sin(hR).
