We are running into some strange behaviour using the online evaluation of the bag files.
Attached, two links to bag files. The position information in these bags is (as good as) identical. We only changed the orientation. The plots online however show that the x and y axis are inverted.

We understood from the technical annex that scoring would be purely on position errors, so we do not understand the dependence of the score (and the output plot) on the rotation information.
Feel free to verify these outcomes with the bagfiles attached.
