Corrupt Hlt1 SelReports substructure information
Inspecting /calib/online/tmpHlt1Dumps/LHCb/0000269942/Run_0000269942_20230711-201516-327_PLEB01_0082.mdf I notice that the substructure of SelReports for lines which make two-body vertices appears corrupted. Specifically, the second track in the substructure list appears to always have reasonable LHCbIDs but nonsense track parameters. E.g. the first track seems filled with reasonable information
