Model of Sgr A*’s diffractive scattering of Sgr A* at 320 GHz based on parameters from J18. Here, ρPR is the approximate (u, v) radius predicted for our putative geometric model, beyond which the photon ring signal is expected to dominate for Sgr A*’s observations at the chosen frequency. The (u, v) coverage in white is of the putative EHT 2025 array (see Table B.1).
