Azimuthal angles discussed herein shall bemeasured in a counterclockwise direction with a 0starting point and a full 360а Polar angle is a ports angular displacementabout a horizontal axis.This horizontal axis of rotation intersects the portҒs focal point and lays on the focal plane which is in turn perpendicular to the chambers main Z axis. Polar angles are measured in a north to south direction on a 180Ұscale between the focal points vertical axis and the portҒs center line,figures 4,5 and 6 on facing page.The north position is 0and the south position is 180а.A port is said to have a 90 polar...
