Here again are some notes from the meeting, sketchy and by no means
complete, just listing some of the issues raised through questions
and discussion after each presentation.

Daniel Heuchel - PandoraPFA on AHCAL 2018 Data Studies - Update
---------------------------------------------------------------

??:   (9) 2-particle performance looks better that 1-particle's
DH:   never tuned for 1-particle
      Pandora expects 2 particles, partly biased
FeS:  1-particle performance not well defined in Pandora

FrS:  growing "confusion", not usual use of the term
FeS:  "unassigned" would be a better term

RP:   differences MC-Data more non-linear
DH:   Pandora 'prefers' more clusters as one of the reasons
RP:   but often small energies for extra clusters
      this also affects energy resolution
      saturation effects in clustering?

MC:   (10) comment on efficiency and possible cluster sizes

FrS:  MC has higher tendency not to take cluster
      .. leading to more 2nd neutral clusters?
      look at E lineraity to check this
      (8) multiplicity>2, a hierarchy issue?
      what about MC, angle hits, energy distributions?
      is an energy cut needed, same for all beam energies?


Roman Poeschl:  CALICE and GEANT4
---------------------------------

Using too often the older versions
technical difficulties to use the new most recent
change to versions 10.3, 10.4, or latest 10.6?
GEANT4 Validation Portal should be explored.  What is needed?
Need info from GEANT4 on how to handle the time info.
Shower separation studies to be done.

MC:   outdated, now interested in v10.6
      a real problem, with manpower as show stopper
      (both for GEANT4 (eg old versions) and CALICE),
      10.3:  drastic differences data/MC, enery dependences
      move to 10.6 as fast as and if possible

RP:   CALICE analyses should urgently consider newer version

KK:   yes but we follow ILCSoft for all LC data
      then a serious problem if new version not handled

EB:   use a wrapper?

FeS:  need support for ILCSoft

RP:   address issue in next TB meeting:  overview & manpower

Concluding remarks
------------------

Thanks again to all for lively participation, feedback and general discussions.

Todo:

1) consider writing CALICE Notes and papers from your analyses!
2) identify analyses in need of new GEANT4 version
3) prompt EB's for progresses in papers in the pipeline

Stay safe.  Relax for new start in New Year when we meet again.  Best wishes!
