I have just done a CM which I feel is not totally correct. There is one dot on the CM that stood out in particular, however as this dot appeared above and below the surface when I zoomed up and down. I marked the CM as "No Track" as this dot appeared above the surface. I then recieved a point for an incorrectly answered CM.
Correct me if I am wrong, but I thought you are not meant to see tracks when you are focused above the surface?

You are correct that it doesn't make sense to see a track in focus above the surface, because above the surface there is nothing for there to be a track in.
But in this movie I don't see that the inserted feature is in focus above the surface, merely that there is something right on the surface, so it would be visible above it, but out of focus.
The calibration movies in Phase 2 contain inserted features that are copies of the candidates found in Phase 1. Note that I call them features rather than tracks, because we are not yet certain that they are in fact tracks. But they are candidates for particle tracks because they have some of the right features of a track.
