[BLAST_ANAWARE] minutes analysis meeting 06/09/04

From: Tancredi Botto (tancredi@lns.mit.edu)
Date: Wed Jun 09 2004 - 17:47:04 EDT


NM: shows inclusive asymmetry data from D2
        _ shape well reproduced by DGEN
        _ seems a factor 2 off
                _ will check definitions, sync to show_deep_asym conventions
        _ how is "eepn" channel in dgen different from "eep" "een" channels

GT: some numbers about target flow
        _ from ed elastic , V14 open/close buf/abs, 40 and 60 cm
        _ assumes warm inlet
        _ somehow inconsistent with H-elastic data !
                _ will need to check also with eep

AM: incorporated background subtraction in deep analysis
        _ comparing 60 and 40 cm cell data, different spin angle
        _ vector pol has not changed with 32 deg angle
        _ overall vector pol 0.55-0.6
        _ figure of merit

long discussion about eep/T20, optimum spin angle, need to make decision
about spin angle and cell soon.

AS: shape of Ge/Gm still sensitive to analysis
        _ needs new tof offsets
        _ coordinating with wang on bats code

EG: vertex 1.8 cm with left e-, 2.0 right e-

discussion about wch calibration and track fitting/finding.

_ Discussion over taylan's method emphasizes its originality.
        _ Note, his calibration may compensate for tracking angle effect.
        _ can try on top of existing or new calibs to extract incremental
           changes
        _ Chris also having a go at new t0, x0.

_ Need more time for testing of new wch calibration methods

CC: the bug on electron pathlenght is fixed
        _ lrn still crashes (Core dumps) on epics data
        _ working on it

PK: tof offsets ready to go, ready for recrunch.
TB: _ tdc offsets recrunch won't wait for bats and/or calibrations
