So this is an updated result from what you showed at June 2021 SK CM?

What exactly has changed? So far I only see the addition of fixing labeling of image 758 (though the image ID labels on overhead plot seem to have disappeared so I can't easily tell how it's changed, but looks like not much, comparing the figures). Then I see the results also changed slightly, e.g. Radial (tangential) position error mean from 4.17 (1.28) to 3.74 (1.15) cm.

Could you make a report describing these developments?

Also, should WCTE stuff be in separate PR? Or no need to review?

Oh sorry, the SK stuff was from December 2021?? Now I'm more confused...
