        "note": "The geographic range — how far off a light or landmark first peeps over the horizon — is the sum of two horizon distances: your own (from height of eye) plus the object's (from its height): 1.169·(√h_eye + √h_object). A 100 ft lighthouse seen from a 9 ft cockpit lifts above the sea at about 15 nm. It is purely geometric; whether you actually SEE it also needs the light's luminous range (its brightness) and the visibility.",
