Hi Han,

Thanks for making the test images. I'm confused about the orientation. When displayed in AIJ or DS9 with no image flip and no image rotation, they show upside down (i.e. flipped in the Y-axis). Is that expected? What is the key image distinction we should see when separating the images into individual R, G, and B single color images?
