Yes, a paper that STARTED WITH ALFVEN's coronal loop and plasma pinch theories and numbers! They proceeded to use Alfven's pinch techniques to demonstrate that discharges and double layer breakdowns can and do produce gamma ray burst that are polarized.
You said "quantitative evidence." What quantitative evidence was there in that paper that supported your assertion? Was there a
single example of, say, an analytically-derived number relating to solar flares that was then compared to an observationally-derived relating to solar flares, and shown to be within a reasonable error band? If not, then there was no quantitative evidence to support your assertion.
The paper contained neither an analytically-derived nor an observationally-derived number related to solar flares.
We also have direct evidence (granted it's in a second paper) that solar flares produce the same types of polarized gamma rays. Would you be happier if I asked if the TWO papers combined provided evidence that solar flares are caused by electrical discharge processes?
That would have been a very different and much more involved question. I haven't even glanced at the second paper yet.
I spent a lot of time on that SERTS data that you linked and, IMO, it provided no support for your assertions (and actually contradicted them). And we went over it at length, and AFAIK you keep citing the SERTS data as if it supports you.
You went on at length about the power of RD images to show terrain through the photosphere, so I made & posted an RD image that appeared to show terrain by combining two pictures of clouds (so that there was no possibility of 'real' terrain in the image). You ignored it.
I spent a fair amount of time on that first Dungey paper, in which, again, I did not find any support for your position, though IIRC, you finally said that the paper was relevant only for terminology. I'm not sure if you're currently citing that paper by Dungey or a later one.
I spent a lot of time on that SDO picture. I made a computer model to show how there should be a gradient to the green 'atmosphere' if it was truly an atmosphere. I even duplicated the overall SDO image (well, the top left quarter of it) by combining single-color pictures from other sources with a disk-shaped filter to give my image the green disk, before we got confirmation from NASA that the disk was added for aesthetic reasons. AFAIK you're still claiming that the green disk supports your position.
So, no, diving into another paper isn't high on my priority list.
