First one (http://stardustathome.ssl.berkeley.edu/ ... d=841740V1) is not very promising. The "track" I noticed is near the upper right corner (roughly X: 475, Y: 75). The tiny "track" comes into focus later than the surface irregularities on the left, so I clicked it. It turns out there is only one more (out of 441) that identified the movie as having a track. My opinion is that either the surface is tilted so the feature comes into focus later or it's just because it's so tiny. Many small features on the left is visible on the highest focus while this one is not, though.
Second (http://stardustathome.ssl.berkeley.edu/ ... =2800944V1) and third movies (http://stardustathome.ssl.berkeley.edu/ ... =2800944V1) are better, but still have less agreements than I would imagine (15/448 and 46/419, respectively). In the second movie, please check the center (roughly X:300, Y:250). Again, it's tiny. Third one is more noticeable on the left (X:75, Y:200) with a more visible "tail".
Probably they are nothing, but as a newbie I wanted to have some feedback
