Mass distributions of interstellar impactors derived from the instrument calibration with the calibration parameters listed in Table 1 (solid histograms; from Altobelli et al. 2005a, 2003, 2006, 2016; Strub et al. 2015). Dashed histograms show the fluxes shown in Fig. 4 derived from the model. The model curves are normalized such that they contain the same number of particles as measured by the spacecraft detector in the time interval under consideration. Vertical dashed lines indicate the detection threshold assuming an average particle impact speed derived from the model (Cols. 5 and 9 in Table 1); for the Cassini 2 interval the upper detection limit for theCDA CAT is also shown. Particle radii are indicated at the top.
