Thanks Terry 😊
In PixInsight all calibrations are done before debayering, so they are correcting the pure RAW files.

I assumed it would. 

This is always the recommended way of doing the calibration because 1) you need to ensure the images are converted the same way to color (otherwise calibration mightn't work) 2). it's a lot kinder on the computer with file sizes 1/3 the size.

You're right in the raw state all pixels correspond one to one and nothing has been manipulated in the image data at this time yet. The smaller file size is a nice side effect, while the amount of pixels is the same as in the RGB image (If you are not debayering as superpixel).
In the next part, I will go through the whole calibration, alignment and stacking process.
