Apply 5-point circular moving average to reach_km values before
rendering the boundary polygon. Eliminates sharp spikes caused by
isolated terrain anomalies in SRTM data.
- 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)
- Viewshed uses propagation score to set max range (ducting/NLOS distance)
- Terrain checked within radio horizon; clear paths get full atmospheric range
- Detail panel moves from map popup to sidebar for better visibility
- Panel shows instantly on click with loading state
- Dark opaque background for readability over map
- Factor analysis section explains each score with contextual descriptions
Replace generic range circles with actual LOS coverage polygon computed
from SRTM elevation data. Casts 180 rays (every 2 degrees) from the
clicked point, runs Fresnel/diffraction analysis on each, and renders
the reachable area as a Leaflet polygon.
- Viewshed module with haversine forward, terrain sweep, async compute
- Antenna height control (default 8 ft) in map panel
- LiveView start_async/handle_async for non-blocking computation
- Remove signal icon from band selector
