position used in finding the hori-zontal distribution and readings of the candle power taken for0, 30, 60*, 90*, 120*, 150* azimuth. The lamp was then rota-ted through 15* in a vertical plane and readings again taken for0*, 30*, 60*, 90*, 120*, 150* azimuth. This was repeated through-out 360*in the… … The Curve AGEBA. in the figure above represents the ver-j| tical distrioution for a certain degree azimuth. Prom the points^ where the prolongation of the radii AE, AP, etc., meet the cir-I cumference, horizontal lines were drawn, and on these from thepoint where they cut the perpendicular, ab,…
