... November 5, 1997 . The Milky Way's Gamma-Ray Halo . Credit: D. Dixon ( UCR ), D. Hartmann ( Clemson ), E. Kolaczyk ( U. Chicago ), NASA . Explanation: Our Milky Way galaxy appears to be surrounded by a halo of gamma rays . Gamma rays are the most energetic form of electromagnetic radiation , with more than a hundred thousand times the energy of visible light, but known gamma-ray sources don't account for the diffuse distribution of this high-energy glow. ...

Look at antenna cross­coupling: S 0 = M \Delta S Standard (and OK) assumption: ''circular'' feeds are orthogonal but elliptical -- then this is simpler (e.g. D. Stinebring, Ph. D. Thesis, Cornell 1982) I 0 = I Q 0 = Q \Gamma V ffl 0 cos OE 0 U 0 = U \Gamma V ffl 0 sin OE 0 V 0 = V + Lffl 0 cos(` \Gamma OE 0 ) where ` is the incident position angle, and ffl 0 and OE 0 are the cross­coupling parameters. ...
