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