Example MET Selection (selections.example.met)

A minimal worked example showing how to write a selection. Import with:

from AnalysisG.selections.example.met import MET

MET

MET is a SelectionTemplate subclass that records the missing-ET value for every event that passes the selection.

Output attributes (available after the analysis run):

Attribute	Type	Description
missing_et	dict[str, float]	Maps event hash string to the MET value [GeV] for each passing event.

The underlying C++ class (met in met.h) stores map<string, float> missing_et; the Cython transform_dict_keys method converts it to a Python dict after each event via as_basic_dict.
