The snippets below demonstrate how to split MC events originally intended for the 2024 data-taking period into orthogonal parts that can be used to simulate the 2024, 2025 and 2026 data-taking periods. The splitting is done event-by-event and only depends on the event ID. The underlying algorithm is
- fast,
- deterministic (also across different working groups for synchronization purposes),
- unbiased towards the event ID, and
- splits events into three parts with frequencies that reflect the relative recorded luminosities in 2024, 2025 and 2026.
