3) Round table
----
Markus: LHCb has asked for a new tag with the latest PRs. A new tag will be provided.
Andre: All discussed in the points above. Will provide the tag after the ion issue is solved.
Timescale for the new tag is tomorrow. Will go into LCG 103.
Frank: Got the GFlash examples running. Now he is missing the interface to ddsim.
Jurai: Experimenting with CLD. Calorimeter hits in edm4hep produced directly with DDG4 are OK.
In key4sim Geant4 the hits have no contributions.
====> To be looked at by key4hep.
Thomas: Cross-section and weight PR hopefully passing....
