ONE CORRECTION:

The Planck map of the temperature distribution of the cosmic
background radiation is a projection map.

The twisted white curve shown in that projection is really a circle on
the sphere surface.

It was said also in the text of the anomaly picture that the twisted
curve drawn is the ecliptic circle.

So light cone circles are real circles and they are not twisted.
