Graham McIntire 9fea93f59c Show earth curvature in contact elevation profile ... Terrain elevations now include the earth bulge correction, so the profile visually humps up in the middle relative to the straight LOS beam — showing how the curved earth rises into the signal path. Uses actual k-factor from HRRR refractivity when available, otherwise standard 4/3. For a 300 km path at k=4/3, the midpoint bulge is ~2,650 m (8,700 ft).		2026-04-11 14:55:21 -05:00
