3D Plot of Meteor Data

[Dan Cordell]

This is the 3D plot of the meteor data sample that Tilvi sent me. Height = counts.



Thoughts?

I think that'll go great on the presentation--it gives a very good visual idea of what is going on. Now we just need some more data so we can pick the best examples to show.

Also, here is the same plot using bars (and in a different perspective):

What you have in the plot is light intensity vs. position. Combining this with what Lior did using the double CONCAM meteor, allows you to plot the light output vs. altitude. The light output is connected with the mass loss from the meteor by ablation, so using this kind of plot one can see where the ablation is greatest.

What this scientifc result is lacking is a measure of the meteor deceleration. This is a result of the atmospheric drag, but the results obtained so far show that the meteor speed does not decrease very much during most of the luminous train. The deceleration is sudden and near the end of the luminous part of the trajectory.

From Tilvi's post about the sporadic meteor:

We can see that there was only one main explosion on this meteor, unlike the one above.
