Poking at Steve, I get at last that he calcs the color intensity in Kerr coords, which is not right in near-fields !!! My apologies, and we will soon have all this RIGHT. I emailed Burinskii. WE ARE TALKING ABOUT THE SQUARE ROOT OF -D, the determinant of the Kerr transform.

I am confused but working at it. On one hand, scalars are invariant.

However we are looking at ENERGY per UNIT VOLUME. Energy is the

scalar.

Right now I feel stupid and slow, as I can’t see this all the way thru. I can say magnitude of any radial vector, if you start with a covariant form as do the DK fields, is E_r E^r, which is the square of the covariant form, times g^rr. IN KERR, THIS IS (r^2+1)/(r^2 +cos^2).
