How is a crater 280 feet from the threshold, 60 feet left of the centerline, with a diameter of 40 feet written?

This notation encodes crater location by three pieces: the distance from the threshold, the side of the centerline, and the diameter. The string starts with C, then the distance from the threshold, followed by L or R to show left or right of the centerline, then the offset in feet, and finally D with the diameter in feet. For a crater 280 feet from the threshold, 60 feet left of the centerline, and 40 feet in diameter, the correct form is C280L60D40. The distance is 280, the side is left, the offset is 60, and the diameter is 40.
