Yet another CSHKP model illustration, but worthwhile here
because it tries to identify some of the Doppler signatures that one
might follow.
It omits the known SAD phenomenon,
which would be up in the "reconnection outflow" regions (below and, though
not shown here, above) the hypothetically unique X point of 2D reconnection
theory.
This is important because XUV imaging spectroscopy already exists and may get
better, so that a combination of geometric knowledge (the imaging) and
kinematic knowledge (the Doppler shifts) may really show us the way things
work.
We should also bear in mind that these complexities will occur in
stellar events that may have physically
similar components.
