Richer comment on 900 GHz: Beam deformities at the higher frequencies will of course dominate anything
originating in feed leg rotation differences.
AW: At 300 GHz, or workhorse frequencies, this may not be true.
JGM: Coherent structures on one antena or another complicates things. There were such structures seen.
Ripple structure on Vx antennas. AEC did have such a set of panels built to the wrong focal point.
These sorts of structures were not taken into account.
Conclusion: All agree, impact on science of different feedleg rotation position is probably minimal.
On the Hills memo on the scattering cone: Bacmann agrees.
