Splitter Channel workflow
How does integration work with splitted channel calibration frames? What is the difference between sigma clipping, winsorized sigma clipping and linear clipping?
The splitted channel option in calibration is only needed if you want to combine OSC/DSLR camera data with monochrome channel data. Then you would need to split your RGB data. And process the splitted channels together with the monochome channels from the monochrome camera separately. So integrate all red data, then all green, then blue, then register the R,G,B integrations and then import them into the RGB Combine tool to create a final RGB image (or LRGB for instance).
