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 Confusion Studies for Two Particle AHCAL Events and ILD Jets
----------------------------------------------------------------------------------------

Katja:    about data validation
Gerald:   slide 24 & ILD


Shubham Pandey - Status of the pion analysis of the combined HGCAL+AHCAL setup
------------------------------------------------------------------------------

Marina:   slide 27, should select deeper layer

Daniel:   shower start finder & cut variable

Frank:    slide 25:  is .. a constant (vs global) to match MC

Katja:    mention publication

Olin:     choice of simulations dedicated?  EMN (CMS)

Roman:    which GEANT4?  10.3 -> 10.4.3

Roman:    radial profile shows discrepancy, zoom around beam pipe, check with GEANT


Olin Pinto -Study of shower shapes recorded with the CALICE AHCAL in 2018 Test Beam Data
----------------------------------------------------------------------------------------

Marina:   negative values?  Gamma function used?


Fabricio Andres Jimenez Morales - Implementation of the digitization for the SiW-ECAL
-------------------------------------------------------------------------------------

Katja:    negative times from earlier hits?

FC:       something about time period (forgot!)


Adrian Irles - Optimization of the LCIO RawCalorimeterHit for CALICE
--------------------------------------------------------------------

Roman:    important, Technical Board should be involved
          how to simulate bunch trains?
          make (very) sure code will not crash

Gerald:   replace raw cal hits?
          since we are the only users, it should affect only us

Katja:    good mode, cycle number should be stored or is it already available?
          even ID  could cover many cells, info needed for calibration

Roman:    should be reviewed(?) before next collaboration meeting

Taikan:   array structure instead of .. ?


Sergey Korpachev - ANN-based prediction of shower properties using global observables for validation of Geant4 hadronic models
------------------------------------------------------------------------------------------------------------------------------
 
FC:       which are the hyperparameters of NN?
          slide 15:  what is the small side peak on left plot?

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

Thanks again to all presenters and participants!

Don't forget to consider writing CALICE Notes and
papers from your analyses!

Best wishes!
