Thanks for the revised data Frederick,

I re-ran the analysis with the revised flat files, it definitely changed the results for gains 60, 80, and 100. Onto the google share folder I've uploaded a new data output file, Fred_ASI-6200MM_Center-Revised-2024-03-16.dat which can be compared with Fred_ASI-6200MM_Center-2024-03-15.dat if you care to see what changed in the results.. A screen shot of the graphs from new analysis is attached here (and a copy is also on the google share).

The only substantial difference between the ZWO data and results from this tool have to do with identifying exactly where the mode switching occurs in this camera (that abrupt drop in read noise). Per ZWO the mode switching occurs at gain 100. From the data we used in my tool I can only say that happens between 80 and 100. If you are curious to know exactly where that switch occurs, we would need to include bias and flats that are slightly below 100.

But, I think my next effort on this project is going to be developing a process that will drive the acquisition of the bias and flats images. In that process I hope to be able to automatically identify where cameras are doing mode switching. I also need to develop some processes to resolve issues with white balance settings on color sensors. So if you have no urgent interest in knowing where that mode switch is occurring, that's fine; hopefully the data acquisition function will be able to find it for you when I get this tool to the point where it can be deployed.
