I also show the usual plots of relative velocities....
Line color code:

- Pink - Io / Ganymede
- Yellow - Io / Callisto
- Green - Europa / Ganymede
- Red - Europa / Callisto
- Blue - Ganymede / Callisto
Finally, here is the velocity and acceleration audio:

Continuing study of SDSS image of M13
I took this image of M13 from the SDSS:
I then calculated the distance, in pixels, between the position of the star and what I determined to be the center of the cluster. Thus, my calculation is the radial distance of the star from the center of the cluster. I then converted this distance to an audio frequency and the brightness to an amplitude, and added them all up to get this:

I then took the ten closest stars to the center and made a tone with them, and then the next ten, and then the next, and the next until I had eleven different tones each containing the audio distances of ten stars. In what you're about to hear, I run each 10-tone sound for 14 seconds, with one second of overlap. No idea what this means, if anything. But I sure do like the sounds produced.
