/ Abstract
Significance We present the low-latency alert infrastructure performance and data products based on an end-to-end MDC designed to prepare for O4. We aim to provide a useful reference for the broader astronomy community following up on GW alerts, and aid in interpreting the data products made public by the LVK. The MDC covers a dense sample of compact binary coalescence (CBC) events similar to those we hope to observe during O4, demonstrating up-to-date results for the public data products. We strive to maximize the efficacy of multimessenger follow-up searches by helping astronomers utilize our data products to their full advantage. The description of the alert infrastructure may be used as a reference for astronomical experiments targeting similar timescales.
