Hi Lawrence,
Thank you for sharing the datasets. The one thing that I find a little bit odd, is some very pronounced mottling. Something is not quite right here. Did you dither between frames? I can also spot denabering ("zipper") artifacts, pointing to the use of an unsuitable debayering algorithm (did you select AHD by accident?).
Have a look here for recommended
DSS settings and
here for tips/do's and dont's with regards to acquiring good datasets. For example, I note an apparent lack of flats with vignetting and dust donut readily visible. Flats are really not optional...
In 1.6, you can remap the channels on-the-fly using the Matrix option, which I did. Mapping RGB to BRG seems to do the trick;
