Table: Event messages used at GSI. The relevant event numbers for triggering hardware are shown in bold. Unless explicitly mentioned, other event numbers are out of the scope of the b2b transfer system and only given as bonus material. Messages distributed by the bunch-2-bucket system use the parameter field for data transfer (click).
