But then why are they still tracking it?
If you refer to that animation, it's just the continuation of ISON's trajectory, which has been calculated long time ago. Even after a comet
disintegrates, you can still point to the place where it would've been now, or in the future.
As for the real tracking, detecting and studying ISON's debris allows astronomers to learn more about what it was made of, and how it broke up. It's
like crime investigators looking at the crime scene and the dead body to learn what and how it happened.

Good point have you seen this thread?
NASA knew about this comet back in 2005 anyway. There is no way they could have had deep impact in prime location for perihelion.
There's no way NASA or anybody else could know about this comet in 2005; it was too far away and beyond the capability of any telescope we have.
Deep Impact was approximately 150 million km from ISON, hardly a prime location. neo.jpl.nasa.gov...
