March 08, 2002
University of Connecticut
Storrs, CT

Present: Scott, Craig, Dan, Richard, Dan, Mihajlo.

Dan Steiner:

• has no new pictures. He improved the cluster-recombination performance by using the log-energy weighting. The weighting refers to haw the centroid is found. The non-linearity correction gets redone after the clusters are put together.

• reports that tagger offsets are in maps. BGV is reasonably balanced and tdc offsets are going into maps. No need for clustering because veto is only on tdc value. A +/-15 ns window is used, contains about 100% of the coincidence, very few randoms. To prevent false veto, two BGV counters are ignored, +/-1 around pixel. Single pixel and single tagger hit are required. On good pi0 sample veto rate is 30%. He will write a note.

• is working on getting software working. Will post minutes on web and send around email containing the link.
