OK. I tend to agree that the two bands were emitted (on average) at different
times. But there are other possible explanations and implications according to
BaTh.

Much of the 'apparent' ~80 phase difference between the two bands can be
explained by substituting different 'yaw' and 'eccentricity' values to produce
the two luminosity curves.
This actually becomes somewhat complicated in BaTh and I haven't thought about
the possibilities yet.... so give me some time..
