Hello,

Yesterday at the meeting, we had the discussions of events with low confidence level (<1%) from  the kinematic fitter. To address those discussions, I looked at  and am now sending out a file with the following information:

1. The gamp input 4-vector and the reconstructed output 4-vectors (PART0 and PART1 banks).

2. The opening angle of the phi, i.e. the angle between the K+ and K- from the decay of phi

I have labeled the events with the pdf page numbers this time around, so it should be easier to track the tracks.

To look at the pdf file with CED images:

For a recap of the meeting:

None of the tracks have been misidentified though there is sometimes huge discrepancy in the input gamp and the reconstructed output phi opening angles.

Regards,
Mukesh.
