It's not even marginally correctGarland,
I will agree that my use of 'Specular Highlight' to describe the
circle of reflected light is only marginally correct.
True banding only happens in one direction.
The sensor is read out in only one direction. So you can have vertical banding or radial banding depending on the chip and the supporting electronics and how they read the data out of the chip.
The one thing you cannot have is "radial banding"
IMHO, that's just good old-fashioned blooming, and something I'd expect from any camera under those tortuous conditions. Better than most, in fact.
