Hi
Can AA8 combine with sigma clipping.
There are a normalization sigma clipping i dont think thats the same, as in PI, DSS or Siril ?

That's fully implemented in AA8 - check out the AA8 demo.

Thank's Dunmunro
I already have & use AA8. But i don't find sigma clipping.
Only sigma and sigma + sum

I read through the Siril documentation and it seems that AA8 implements sigma clipping in much the same way.
