Suggestions for 'Slanted' Aerogel?
The movies I find hardest to be confident about are the ones which appear to be slanted.
when NOTHING is in focus I put them down as bad focus, but with slanted images the focus of the surface seems to flow from one side to the other - I have yet to find a track in one of these and am wondering if I am doing something wrong. They have all been 'no tracks' and I am basing this on going from the bottom up and looking for potentials on the lower levels - this should be ok shouldnt it? the track should go almost right the way through the areogel?
Cheers

Well the most important thing to note by a project like this is that a good amount of the calibration/testing movies were made by shooting dust into the aerogel with a machine. We simply don't know if the tracks would go all the way through or not because we have almost no "real" data to base that on. In fact, The movies supplied in the training and calibration movies could look completely different from the real deal. It's important to note (and also, to keep you on your toes) that there is a lot of unknown in the equation so far so keep looking sharp and do your best and of course, more importantly, have fun.

I've seen a few of those myself. None with any tracks so far.Belinda wrote:The movies I find hardest to be confident about are the ones which appear to be slanted.

I evaluate them zone by zone, comparing the particles to those nearest to them rather than to the whole movie. But I'm pretty careful not to use this approach on regular movies that are not slanted.

I had a perfect example yesterday. I wish I would have written down the number.cosmicrocker wrote:I'm glad someone mentioned this. I analyze them just as icebike described. I suspect a lot of people may not recognize a tilted or irregular surface.
Offering 3 DustBunny Points to the first person that comes up with a GOOD Obviously Slanted Movie number and posts it here.
oh! oh! me! me! here ya go guys: movie 28160 slanted straight up and down (low side is down).

I wonder how many people were tricked into clicking that dot at the top which only comes into focus near the bottom of the focus range. If you didn't catch the fact that the whole surface was slanted you could really get fooled.
Three points, and a bonus point for promptness.

Another one, with a nice regular slant... except at top left: Movie 47394.
Seems some people have already clicked the black dot...

I got the movie ID from another thread (don't know which one anymore) where someone said he had clicked it, and that according to his events list there were a few clicks for that movie...icebike wrote:How do you find that out? (other than clicking on it yourself and getting it added to your events list).mover wrote:

That's why I said "seems" in my post, since it is not in my events list. I didn't get that movie and if I did I wouldn't click that black dot myself.

I'm with TimStrange on this. Just treat each level apart untill you are completly down. When every bit of the movie can be checked below surface click "No track" (or the track if its there ) else click "Bad Focus"
Also check this thread on bad focus: http://stardustathome.ssl.berkeley.edu/ ... .php?t=645

I see absolutely no reason for this situation. The other side of the glass has over a million hits surely somebody could have use some of those for test images...We simply don't know if the tracks would go all the way through or not because we have almost no "real" data to base that on. In fact, The movies supplied in the training and calibration movies could look completely different from the real deal.
I've found only one classic as shown track. It looks just like the test but much clearer. Don't know if it's real or not but noticed lots never found it. I think 12 so far found it out of over a 100 that viewed it. I'd say anything that comes into focus when everything else is going out of focus is suspect.
If it's actually inside the glass then it's suspect. Unless the glass is not perfectly clear there is no way to explain how it got there then.
Everything I have found others have also found. So must be doing something right. They may turn out to not be valid but the thing is from the information given they cannot be ruled out just yet so somebody has to re look at them to eliminate them. Maybe a better view or different lighting angle will eliminate it but till that happens it looks to me and others that it's actually inside the glass.
