Detailed Description

The hit system records a core set of per-step quantities unconditionally and can optionally record additional per-step information controlled by a fixed-size bitset.

Always recorded (independent of the bitset):

• local and global positions (G4ThreeVector)
• energy deposited and time
• detector dimensions (via GTouchable)

Optional information is controlled by HitBitSet, with one bit per feature group. The bit meanings below define the expected mapping and help keep binary compatibility and analysis conventions stable.

Definition in file ghitConventions.h.

Note

The bit index meanings are documented below. Some higher bits are reserved for future extensions and may not yet be populated by the current implementation.
