One-Mile Telescope 2026-10-18
The One-Mile Telescope used three steerable 60-foot dishes: two fixed, one rail-mounted. The movable–fixed pairs supplied two baselines simultaneously. Twelve-hour tracks at successive rail positions sampled projected spacings. Phase-switching receivers measured in-phase and quadrature correlations; adjustable delay and phase rotation compensated tracking.[ref]

The readout was correlation versus time. Reference-phase subtraction should leave constant point-source phase; position offsets produce predictable variation. A source near the field's declination supplies a collimation check. Structure, instrumental error and sampling artefacts need separating.[ref]
