Notes. Mass regime means the limiting mass for which the fluxes were calculated, Nast and Ncom are the numbers of observed asteroidal/cometary meteors, Aeff · tobs is the time-area product, and Fast and Fcom are the fluxes of rocky/cometary meteoroids on cometary orbits. Remarks in parentheses indicate different combinations of used data or time-area products in the calculations. The results are provided together with 95% confidence intervals. For case Nast = 0, the one-sided 95% confidence interval is provided. Data from Vida et al. (2023) are provided for reference.
