If the B-mode sky plots could be Fourier transformed what would be a plot of the lowest order B-mode harmonic plotted on a sphere look like?(adsbygoogle = window.adsbygoogle || []).push({});

I guess we need two functions of spherical coordinates, one function for amplitude at points on a sphere and one function for the orientation at the same points on a sphere?

Is there a hypothetical "gravitational wave" that gives rise to this lowest order harmonic?

Thanks for any help!
