The weighting function for the time average is derived from K. Libbrecht and H. Zirin, Astrophys. J. 308, 413 (1986) with weights equation presented where δt is the time difference from the central observing time, τ = 4 min is the half-width of the filter, and Δt = 9 min is the half-length of the filter.
