Simulations of the HLV and HV configurations for O5 estimate GW detection rates at a signal-to-noise threshold of 8. The dataset provides skymaps and essential parameters for multimessenger studies, along with a Python script to classify BNS, BBH, and NSBH events by mass (with neutron star masses defined as less than 3 solar masses, and black hole masses as 3 solar masses or greater by default). The summary.rst file provides statistics, including detection rates, luminosity distances, and other key parameters. For full details and code, please see the observing‑scenarios‑simulations on GitHub
