NG: Update from Uriel?

UU: Definition of clusters has direction and energy or just IDs cluster?

NG: Building abstract cluster using hep.lcd, calculates direction cosines for cluster itself.

UU: Jason Hanson has program that follows hadron and includes energy loss.  

NG: Aware that FNAL group working on this too?

UU: Not gotten that far.

Only high energy tracks.

NG: Caroline Miltstene's code does this, including curlers.

UU: Having trouble (?).

WM: Caroline gave update at calorimeter session, two weeks ago.  Transparencies are probably posted.

NG: Glad to hear working on it but should touch base with them. 

NG: Update from JP?

JP: Working through bugs.

NG: Get basics w/ INI file.

Talk by Miyamoto, ~3 weeks ago.

Using as baseline?

JP: PDF file.  Some is ambiguous.  Two different geometries for muon chambers.  Sort of picked one that looked easier to code in.  

NG: First iteration debugged, put into CVS.

Try to make part of next release.

JP: Should have something useable.

UU: Least squares fit to pi0.

WM: Kinematic fit?

UU: Yes.

Using BaBar code.

NG: Directions for photon clusters should be quite good.  Good hypothesis for cluster shape.  Algorithm takes moments of energy weighted positions of cells in cluster. 

WM: Can see kshort -> pi0 pi0 ?

JP: Code exists that will find EM shower direction?

NG: In hep.lcd.  Make cluster that inherits from AbstractCluster.  Method in this class that will calculate this: CalculateDerivedQuantities().

NG: Short term plans from EE?

EE: Photon reconstruction.  Looking at H-matrix.

NG: Thought EE could do ki-squared to include transverse info.

JP: Plots exist of discrimination between photons and neutrons?

NG: Not much distrimination power?

JP: Never seen a plot.

NG: Have some plots and will post to meeting page. 

NG: Sim update?

JM: LCIO input.  Working on stable release.

NG: Update on WIRED?

MD: Working on outstanding issues in WIRED4.

NG: No G4 devs.  Just looking at doing range cut.  Not limiting step in PFA.  Should be okay.

SM: Never had endcap in our program (diagnostics).  Can use whole calorimeter for track extrapolation.  Proceeding with conversion.  Hope to have major part done by this week.

SK: When CD burning begin?

NG: 3.5 days behind schedule.

SM: Goal is to finish and put on CD.  Haven't run into any problems.

NG: Update on Pflow analysis at SiD calorimetry meeting tomorrow.

SM: Calculated perfect Pflow for SiD using neutrals.  Will show tomorrow.

NS: Thinking about how to make disk CCDs.  Figured out don't need hexagons -- will use squares.  

NG: Cartesian grid on it.

NS: Found program is losing endcap hits.  4 layers instead of 5.  (bugs)

NG: Probably won't burn CD June 1.  Will have to see how soon after it.

All in cVS though.  Should always build.

No CD CVS package.

MD: For Geant4 CD, made an ant task to get packages from various places.  Check links, etc.
