Design Blueprint: A Five-Thousand-Fibre Spectroscopic Survey Telescope: Multiplex, Etendue and Redshift Throughput Computed from the Observing Cycle

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24150289): A wide-field spectroscopic survey instrument — a 4 m telescope feeding 5,000 robotic fibre positioners over a 8.0 square degree field — is designed from its observing cycle. The etendue is 101 square metres square degrees. With 1,000-second exposures and 180-second field-change overheads, the telescope completes 25.9 tiles per night and records 129,661 spectra nightly, 17.83 million per year, of w Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
