Azimuthal Averaging

I decided to look into the local minima/maxima seen when azimuthally averaging by comparing average about the orbital axis (CM) vs. the grid axis.

Density averaged about the grid axis (Progenitor's polar axis).

Density averaged about the orbital axis (center of mass).

I would not expect these to look different (and they don't), since an integration over $2\pi$ would hit one section of the spiral in either case (except maybe at the poles).

Here is a profile at the same radius:

Density averaged about the grid axis.

Density averaged about the orbital axis.

The averaged profile for the equatorial plane:

Density averaged about the grid axis.

Density averaged about the orbital axis.

Profile at every $\phi$ for the equatorial plane, a 45 degree angle, and the polar axis. Note averaging about the orbital axis (right) enhances the 'overlap' between the profiles.
