From Renee: "I’ve been playing around with EasyLEED and I can’t get it to track the spots properly. I think it’s probably a matter of getting the parameters set up properly, but I don’t know what are reasonable parameters, e.g. for the Kalman position and velocity. The default values seemed to be 0.1 and 0, but when I use those, the integration windows don’t move with energy. Do you know what are reasonable values to use? It keeps saying the fit failed."
