View of a slice through the 3D dust solutions for the sub-solar longitude of 140°. The plane shown is normal to the terminator plane. The direction to the Sun is in the plane shown; the rotation axis of the comet comes out of the plane but has the same projected direction as the Sun direction in this view. The top row shows the dust number density [log₁₀(m^-3)] for the five models (columns). The bottom row shows the dust speeds [m s^-1] for the five models (columns). The results are given for a dust radius of r_d = 1.6 μm and assuming a dust to gas production rate ratio of Q_d/Q_g = 1. The latter only affects the number density values. The 3D shape of the comet is also displayed.
