... These experiments followed the movement of the subreflector as the antenna tipped from the zenith to the horizon. We find, relative to a coordinate frame attached to the receiver platform : ffl The axial movement (axial defocussing) is 0.7mm ffl The lateral movement, (in the focal plane, normal to the elevation axis) is 2mm, and no move­ ment parallel to the elevation axis. ffl A rotation of 3 arcminutes about the elevation axis. ... This gave the rotation of the subreflector, shown in figure 3. ...
