In the course of the migration of the derivation framework to the CA, the prefix for the trigger matching containers was changed to
TrigMatch_. Whilst not technically a bug this will be confusing for analysts and implies that there can be overlap between the tau and no-tau trigger lists, which there is not. Also it messes up the categorisation of the different container types in
checkxAOD.py because the container name doesn't contain
Trig. So with this MR, the prefix is reverted to
This MR also corrects an unrelated trivial mistake which led to MET_Truth being omitted from the output
Since this only impacts the CA version of the derivation framework, which isn't yet in use, this has no impact on any ongoing activities.
