On the suggestion of @mrhardman , I tested the various implict vs explicit options available in `STELLA`. Below, I plot the growthrates from this comparison (the points are as labelled,...

Thank you both for your comments. I may have to delay drilling down these into these issues for a few days as I am at a conference, but they are...

After a lot of playing around, I think I may have some clarity on the minimal ingredients required to observe the discrepancy from the other codes. To do this, I...

I can confirm that this disagreement in frequency was due to runtime. The growthrates with `include_apar = .false.` are significantly smaller than in the previous case, and the STELLA runs...

Thanks for coming back on this. The disagreement in the growthrate is pretty small even in the cases I showed, but the eigenfuntions are very different. Perhaps it would be...

As anticipated by @Scottyujia , the run with the different upwinding agrees much better with `CGYRO` and `GS2`, as can be seen from the eigenfunctions below. There is still disagreement...

Great, it appears there is agreement. The only one that remains is between measures of the heat and particle fluxes, but this is not what I opened the issue for.
