Graham McIntire 49cbe6789c Implement ITU-R P.526-16 terrain diffraction model ... - Replace piecewise knife-edge loss with P.526-16 Eq. 31 single formula - Fix diffraction parameter ν to use standard formula instead of ad-hoc approximation - Implement Deygout 3-edge method for multiple obstacle diffraction - Add dynamic k-factor from HRRR refractivity gradient (falls back to 4/3) - Terrain worker now looks up nearest HRRR profile for atmospheric correction - Update algo.md with P.526-16 methods and k-factor table - Fix pre-existing map_live_test antenna height default (33 ft, not 8)		2026-03-31 16:04:23 -05:00
