GlueX Software Meeting
March 1st, 2005

Attending: David L. Elliott W Simon T. Zisis P Rafael H.
Richad J Paul E. Mac M. Mark I. Elton S.


Agenda:

1. Track Finding (David)
2. BCAL Simulation (Rafael)
3. Status Reports (All)
4. Meeting regularity (All)

--------------------------------------
1. Dave presented some recent work he's done on track finding
   using CDC and FDC data from HDGeant. The slides from the talk
	can be found at:
	
	http://www.jlab.org/~davidl/HallD/Presentations/2005_03_01_2Dtrack_finding
	
	A Hough transfom was described which allows one to identify tracks
	by filling a 2-dimensional density plot and looking for peaks.
	The work up to now is able to sort hits into tracks using only
	X/Y information from the HDGeant cheat codes. The plots shown
	focused only on how well hits were grouped relative to then known
	groupings (via cheat codes). For the future, the z-coordinate will
	be incorporated to further sort the tracks. Also, some suggestions
	were made on how the algorithim might be improved and/or sped up.
   This is an ongoing project.

2. Rafael showed some plots from his ongoing work on detailed BCAL
   simulations using custom Geant3-based code. So far, the study
	indicates that about 6% of the energy is deposited in the
	scintillating fibers with negligible variation with incident
	photon energy. Rafaels slides can be found at:
