- We changed the way the "best" track-tile, track-ribbon and track-gap associations are selected. This causes some small fraction of the events to have changes in a couple of merit variables. The effects are different various cases. Here is a page that summarized the effects.
- We change the way we report the point of closest approach when it occurs at the head of the track. This affects tracks near the sides an top of the LAT with high incident angles w.r.t. the tiles or ribbons. Here is a page that describes this in more detail.
- We use the hardware veto bit directly to count hits in the various parts of the ACD. Before we were using the signal size that was equivalent to the intended veto threshold. This causes a few events to move around in the various counting variables.
- We set an upper limit of 10000 sigma for all associations. This causes a few events with large negative active distances to return to the default values of -2000.
