Getting y-translation from image to image

So Kstars saved the day (night) for me Friday. I couldn't get the polar scope cap off in the cold. I did PA with Ekos only - and it was almost perfect, less than 1 minute of arc according to Ekos. Looking at the image stacking log I see there was no rotation from image to image. However, I notice there is a y-translation. So did I get perfect PA or not? Why is there a y-translation? My camera y-axis is aligned with RA motion.

EDIT: I forgot to mention that I was doing external guiding with PHD2. Here is the stacking log:

So I concluded that both my PA was good and guiding was good, and the translation was due to flexure! I wondered when I was going to hit that problem! :-)
