Simulated dust fluxes for cometary meteoroid trails intercepted by the MMX spacecraft during its interplanetary transfer to Mars (cf. Fig. 2). Simulated particles are larger than \(100\,\mu \mathrm { m}\). Symbols and colours distinguish individual comets: red crosses: 21P/Giacobini-Zinner; blue triangles: 24P/Schaumasse; blue diamonds: 45P/H-M-P; black asterisks: 103P/Hartley; green crosses: 255P/Levy; blue crosses: 207P/NEAT; green triangles: 249P/LINEAR; blue squares: 263P/Gibbs; yellow triangles: 41P/Tuttle-Giacobini-Kresák. The simulations were performed with a 1-day step size for 21P, and with a 2-day step size for all other comets. The dashed line shows the simulated flux of sporadic interplanetary dust particles, see text for details
