BNS inspiral range over time for O4a. Each point corresponds to a time interval of 4096 s, corresponding to the time range of one strain data file. The fast Fourier transform window length used is 8 s with a 4 s overlap. These inspiral range values are stored as metadata for each file in the GWOSC database and are accessible via the GWOSC website.
