To produce caustics, the lens' dispersion-measure depth (${\\rm DM}_{\\ell}$), scale size ($a$), and distance from the source ($d_{\\rm sl}$) must satisfy ${\\rm DM}_{\\ell} d_{\\rm sl} / a^2 \\gtrsim 0.65~ {\\rm pc^2 \\ AU^{-2} \\ cm^{-3}}$. Caustics produce strong magnifications ($\\lesssim 10^2$) on short time scales ($\\sim$ hours to days and perhaps shorter) along with narrow, epoch dependent spectral peaks (0."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.06580","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
