[guide-user] Horizon in Guide

Pierre Laporte Jan 22, 2000

I would like to drawn the horizon around my observatory with the
horizon.dat file. I have walls, mountain and few hills that make
obstruction. When I try to draw the walls of the observatory or some
hills, it sometime appears in inverse, with a gap between the true
horizon and the shape of the mountains or of the walls, as if the
mountain or the wall stand alone in the sky!!!!. I take care to use
the value of –1 as elevation to be sure that the mountain merge with
the ground. Curiously, I didn't have this effect if I use the
horizon.dat file provide with Guide. Could somebody help me to find
out what I am doing wrong……
