Interplanetary-to-interstellar ratio of the measured differential flux of observed meteors on Earth to the corresponding derived power-law fit for interstellar impactors. The linear fit fluxes are depicted for r^−3.0 Jewitt & Seligman 2023 to match 1I and 3I with ISD detections by spacecraft, r^−2.7 to match 1I and 3I with hyperbolic radar meteors, and r^−2.3 to match 1I and 3I with upper limit hyperbolic optical meteors (see Figure 2).
