Notes. The table contains the respective particle’s heliocentric spacecraft speed, vU; the measurement-derived impact speed, vmsr (printed upright), if vmsr > 3 km/s, or iteratively calculated relative speed, viter (italicised), if vmsr < 3 km/s; the most likely reconstructed heliocentric speed according to Eq. (C.1), vrec, hel, assuming the particle came exactly from the boresight direction; the range of the same taking into account a finite detector opening angle of 70°, v rec , hel [ ± 70 ° ] $ v_{\mathrm{rec,hel}}^{[\pm{70}{\circ}]} $; the range of the same further taking into account the error factor, errv = 1.9, of the measurement-derived impact speed, v rec , hel [ ± 70 ° ] , [ ± 1.9 ] $ v_{\mathrm{rec,hel}}^{[\pm{70}{\circ}],[\pm1.9]} $; the local heliocentric speeds for a circular orbit, v°, parabolic orbit, vesc, and hyperbolic ISD orbit, vISD, hel, at that heliocentric distance, assuming the β-ratio that corresponds either to the measurement-derived or to the iteratively calculated mass; and the deviation of the detector boresight from the assumed ISD inflow direction, ΔϕISD, assuming that the dust particle came from the detector boresight with a relative speed of vmsr or viter, respectively (cf. Sect. 6.2.3). All speeds are given in units of km/s. Particles are numbered as in Fig. 9. Italicised values were calculated with the iteratively calculated relative speed instead of the measurement-derived impact speed; for these values the error factor of the measurement-derived impact speed does not apply.
