Agenda
* Nominate Secretary
* Modifications to agenda
* HyCal cluster finding; Dustin, Raphael
* Software port to RedHat Enterprise Linux; Mark
* Event display; Dave
* TAC analysis; Itaru
* More Task List discussion

* Nominate Secretary -----> Aram is the secretary.

* Modifications to agenda ----> No modifications this time.

* HyCal cluster finding; Dustin, Raphael ---->
Dustin:
1) Current status of Cluster Definitions: 3x3 and 5x5 are currently defined in "primex_cluster_db" - do we need larger/smaller clusters? (probably not)
C++ interface to primex_cluster_db exists/works, the code can be found at $CVS_REPOSITORY/src/libraries/hycal/ (has some minor bugs)

2) Cluster Reconstruction Status: Hycal libraries are modified, routines are working for FULL detector
hycal_brun.cc reads detector geometry and cluster definitions from primex_cluster database

To take advantage of the above mentioned changes update your version of hycal libraries and recompile them.

* Software port to RedHat Enterprise Linux; Mark --->
Mark:
1) Environment variables for Red Hat 7.3 and Red Hat Enterprise 3: http://www.jlab.org/ccc/mail_archives/EXPERIMENTS/primex_software/CURRENT/msg00137.html

* Event display; Dave -------->
Dave:
1) Event Display: Event display is being improved, Raphael suggested to add ability to look at arbitrary event.

* TAC analysis; Itaru ------->
Itaru:
1) TAC analysis: Looks like it is OK to place TAC behind the HYCAL. Beam collimators are no good kill 20 % of TAC efficiency (agrees with Itaru's GEANT simulations, suggestions: repeat the simulation with gold converter and make a reasonable cut on photon energies)
