Yes the area must be without start.
We have just be able to zoom into the image and draw a right box.
I think you are going to automatize this function. It is not mandatory on my thinking.
Juste a possibility to draw a box into the image and obtain its statistic would be great.
Hello, I have been working on this issue and I wanted to ask which particular statistics were relevant to be displayed while calculating the stats of the desired area.

I think that the median will be the good estimator for the background. This way, if some faint stars are included into the box, they will be ignored. You can add also the average (mean), but it will be more influenced by residual stars
No need. The draw box intends to select an area of the background without stars.
I am not good at formula but the 3 sigma rules is well know by the astronomers. No need to change it.
Sorry I wasn't able to find time lately. Let me know whether I should output the details in
1. an overlay on top of the image itself ( although limited number of stats, like Width x Height, sigma as this looks messy )
2. a new floating window with the same stats table (similar experience as in Siril )
3. the existing stats panel itself (which alternates between full image stats to selection stats depending on a button )
Attached Image shows how it would look in option 3.
