Signal amplitude of a single dust particle, taken as m v^3.5 as per Eq. (3), for an interstellar (solid curves) and interplanetary (dashed horizontal lines) dust particle and a β-meteoroid (dotted horizontal lines) of mass m = 10⁻¹⁸ kg (yellow lines), m = 10⁻¹⁷ kg (red lines), m = 10⁻¹⁶ kg (purple lines), m = 10⁻¹⁵ kg (violet lines), and m = 10⁻¹⁴ kg (indigo lines). The ISD with m = 10⁻¹⁶ kg (solid purple curve) cannot reach 1 AU due to its high β-ratio; thus, this curve is not visible. No lines were plotted for β-meteoroids above m > 10⁻¹⁶ kg.
