Two Tracks in One Movie?

Two Tracks in One Movie?
When you click on the movie to identify a track, it moves on to the next movie. So, how do I specify two suspected tracks in the same movie?

Re: Two Tracks in One Movie?
Don't worry, I'm pretty sure you only have to mark it for one particle track, and they'll check the whole thing. So if there are two, they'll see them.WeBeGood wrote:When you click on the movie to identify a track, it moves on to the next movie. So, how do I specify two suspected tracks in the same movie?

The one below the triangular shaped fragment is the easy one. The other is harder to spot. If you extent the bottom line of the triangle to the upper right, the second one is 1/3 of the distance to the edge of the frame.Djingis Kan wrote:Could you tell us where to look?
I only found one thing, right below the triangular shaped fragment, which I too would consider a possible track (comming up deeper in the aerogel).

The best way to see this is to focus all the dots in the movie. You can mark this best focus spot (it is the surface) with a click of the mouse button. Now move the mouse up and down between the best focus and the bottom of the scale. All the surface (best focus) dots will get bigger, while the two interior dots will get smaller. Move the mouse fast and it should be obvious.
The other one I found that looks similar to these two is:

This one is very deep in the aerogel.
Hmm, I actually see 3 possible tracks. The two mentioned before:
1. Just below the large triangle shape in the middle
2. About 50 micons to the right of the triangle
3. A small one that comes into focus at about the 7th frame from the bottom. Look at the spot 25 microns from the right and 75 microns from the bottom.
Anyone else see these?

Yeah, I see the one your talking about. Coming into focus in the 7th frame, like it's not as deep in the aerogel as the other two. Hmm, too many tracks in one piece? Maybe it's just a dirty piece of aerogel.nexguy wrote:Hmm, I actually see 3 possible tracks. The two mentioned before:

I know what you all are talking about but are those really tracks? I've noticed several of those and ignored them. They act like normal dust grains, only that they are below the surface. If it were a track it would leave a smudge that always comes visible before (in higher focus than) the actual ring. Do you know what I mean? That's what I think.
