this means in on case the result is in minutes of arc and in the other case in degrees of arc.

Where is found:
"D = 0.0293 * SQRT( h )
where h is the height of the eye above the horizon in meters."
So if the height of eye is, say, 3.5 metres;
0.0293 * 1.8708 = 0.0548
Is there something I'm missing here? Surely the correct answer is 3.3
minutes of arc?
60 * 0.055 = 3.3
this means in on case the result is in minutes of arc and in the other case in degrees of arc.
