Ike Hall has a really good post on data corrections at his new blog.
I’m still in the process of reading through it, but he now has concrete data that confirms what I have believed all along on the basis of the pitcher data I’ve seen, that a uniform correction factor for each park for the whole 2007 season was not adequately addressing the real source(s) of error in the data.

I think that what Ike has done is a step in the right direction. My goal is to get my simulation of the PITCH f/x camera system working and to use the simulation to study how camera distortion affects the inferred trajectory. The other effect that Ike talked about is actually quite easy to simulate, so I will look at that also. I hope to have all this done by the time of the summit.
