Design Blueprint: A Wide-Field Optical Survey Telescope: Single-Visit Depth, Etendue and Data Rate Computed from the Sky-Limited Exposure Equation

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24150330): A wide-field optical survey telescope of 6.5 m effective aperture and 9.6 square degree field is designed from the sky-limited exposure equation. Its etendue is 319 square metres square degrees — the figure of merit that governs survey grasp. A 30-second visit under a 21.0 magnitude per square arcsecond sky in 0.7 arcsecond seeing reaches a five-sigma point-source depth of 24.4 magnitude in the r 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. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
