The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The idea behind this chapter is to collect suggestions and answers to questions that are typically raised by users, aiming to enable researchers to maximize the scientific return from IXPE observations.

C2weakest assumption

That the described strategies, data formats, and processing steps are complete and sufficient to avoid all potential systematic errors when applied to real IXPE observations.

C3one line summary

A user-oriented guide that collects best practices, data formats, and analysis strategies for extracting polarimetric information from IXPE observations.
