Time-dependent detector transfer function, f_det, of the ISD flux that can be measured compared to the ISD flux that reaches Ulysses, for the same four parameter sets as in Fig. D.2, corresponding to particle sizes of a ≈ 2.30 μm (dashed grey line), a ≈ 4.07 × 10⁻¹ μm (dash-dotted navy line), a ≈ 1.67 × 10⁻¹ μm (dotted red line), and a ≈ 5.15 × 10⁻² μm (solid blue line), using daily data points.
