JG G-pole V7

Joachim Gerhard's Guest Editorial in Volume 7 about his G-pole development contains several hand-drawn figures. Although the figures in itself are correct, the references to them in the text are not always correct. The correct references are as follows: Fig.1 is the standard stereo setup where L'  and R´  create the unwanted aditional phantom image as shown; Fig. 2A is the drawing Joachim made for Rick Beveridge as mentioned in the text; Fig. 2B is an improved version of Fig 2A that can solve the beaming problem; Fig. 3 is a typical implementation of a G-Pole. My apologies to Joachim for this confusion.
