VÁ: banding from uneven rotation?

What you say can be modelled by the 35mm lens rotating panorama. (there is
no drum)
Here is a picture made with that camera into the sun (not mine, I wish it
was):

Notice that the sudden flare is there, twice, around the sun. I think that
the edge of the slit has something to do with it (hence the assimetry), not
necessary the drum edge. Maybe we should paint the slits?
Cheers,
Norbert
