It uses a 31.6 lines/mm 63.5$^{\\circ}$ blaze angle \\'echelle grating in white-pupil configuration, providing a spectral resolving power of $R\\sim$65,000 covering the spectral range between 450$-$800\\,nm in one CCD exposure. A prism is used for cross-dispersion of \\'echelle orders. The spectrum is focused by a commercial apochromat onto a 2k$\\times$2k CCD detector with 13.5$\\mu$m per pixel. An exposure meter will be used to obtain precise photon-weighte"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.06090","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"}
