Total mass of planetesimals that enter the feeding zone (or the total mass flow of planetesimals) as a function of their location relative the planet at the time of entry, (see Eq. (20)) for the cases of the planet mass M_p = (yr) 0.7 M_J, (b) 1.4 M_J, (c) 2.8 M_J and (d) 5.7 M_J. Red dotted lines show the positions of 1st-order MMRs and blue dotted lines show the positions of 2nd-order MMRs. The MMRs highlighted with the green line do not supply planetesimals into the feeding zone (see Appendix C).
