Jeremy,
From what I see in your image (the large version you linked) the cockpit area looks to have serious CA. Here is a set of 100% crops:
Cockpit is easily seen... the right of the cockpit, take a look at the tug. The driver's leg shows it, the wheel also shows blue/red shift which is typically CA. On the oher hand, the cockpit windows are likely showing lens flaring... or registration errors... meaning some of the color channels were not properly rendered by the CCD/CMOS as the lens did not bring it to the proper focus (it is hard for me to explain this stuff... others are better at it :-) like Wikipedia or Cambridge in Colour)
Look at the left side, the areas I highlighted show CA (red/purple/blue shifting)
You may have to ZOOM IN to about 500% to make it more obvious.
As far as sharpening, you may be killing yourself with the 100,0.2,0 setting as NO TWO IMAGES require the same sharpening setting. I usually will end up with 5 layers and each with different sharpen setting if needed and then mask the rest. Some areas with super fine detail benefit from super small USM settings while others can benefit more from higher settings.
50,0.5,0 will work VERY WELL on larger areas of contrast with a single pass. Depending on how much small/medium/large detail there is, you should use lower/higher as needed.
The best way in my opinion, but it is more time consuming and even more obnscure to some :-) is using a find edges process and sharpening that. This has a way to AUTOMAGICALLY finding areas that need more and areas that need less sharpening in a dynamic way dictated by the image itself.

Well, I totally know and understand what it is, so that's why I am puzzled I got rejected on these for that reason. I don't see artifacts even at high magnification. The Evergreen I can see a bit of it at 500% magnification. Here is a good writeup

I would agree, not centered would have been more appropriate in my opinion though for that rejection.

That's size ratio. For JP it has to either be 3:2 or 4:3.
