Psi024Alpha

The rendering setup is similar to PsiAlpha, but now also Re{Y₂} is shown as white volumetric clouds. Y₂ stands for the Coulomb part of the gravitational field and is an indicator for matter-like static regions:

Weyl Scalar (complex)	radial falloff	asymptotic interpretation
Y₀	-1/r²	(ingoing)
Y₁	-1/r	(ingoing)
Y₂	(coulomb)	(static)
Y₃	1/r	(outgoing)
Y₄	1/r²	(outgoing)

For this subcritical Brill Wave, Y₂ mainly radiates away with the main Y₄ pulse. Only a small numerical residuum is left at the end.
