Radphi Video Conference 7/12/02

July 12, 2002
University of Connecticut
Storrs, CT

Present: Craig S., Dan K., D. Armstrong, R. Jones, M. Kornicer, Dan S. Scott T.

• Issue: why do 45% of MC events that pass the BSDand fail - probably a timing issue in the analysis of Monte Carlo. I will resolve this issue and write an email reporting by the end of the day.
• They are preparing for about ~15 days of simulation. The suggestion is to simulate all generated events (leave out GEO trigger pre-cut) and then possibly impose it later for analysis studies. The concern is that we not impose special bias in the Monte Carlo.

• studied tagger/LGD correlations -found that the correlations are weak enough that it is not worthwhile to do a DeltaE = Elgd - Etag instead of a simple total Elgd cut.
• He went on to study the BVG - there are weird skews in the BGV vs BSD straight after the overlaps have been masked off. BGV hits look like there are splits in the hits list - needs to be resorted and merged. Dan - Dave will start looking at the calibration of the BGV.

• asked for comments on his recent note on PSF studies.
• Now we are working on getting a good sample of isolated clusters.

• W&M september 6-7 at Williamsburg.
