Greg I'm sorry but I'm going against the norm on this one, the histogram just doesn't look quite right and there appears to be a gradient in there.

Also appears maybe a tad to much noise reduction has over smoothed the result.

I'll probably be shot for saying this but I'd go back to the drawing board on this one with that much data I'm sure you could do a lot better

No offence meant just my point of view take it or leave it

Cheers
