GWTC-4.0: is a target-identical independent PE posterior or reproducible package available for GW230814_061920?

Hi all, I’m trying to conduct a numerical reproducibility study using the public GWTC-4.0 parameter-estimation release. Could someone please advise whether an independently generated posterior representation, or a complete reproducible target package, is available for the corrected/reweighted result below?

  • Event: GW230814_061920
  • Release: GWTC-4.0 PE Zenodo record 17014085
  • Analysis group: C00:IMRPhenomXPHM-SpinTaylor
  • File MD5: 1fab7355ad91d08c88279a76a91664bf
  • Target: the corrected Tukey-window likelihood result described in GWTC-4 Methods §5.10

I’m hoping for either

  • an independently generated posterior samples for exactly this target
  • or a complete reproducible package sufficient to regenerate it without changing the target—exact data conditioning, PSD/calibration treatment, likelihood-correction implementation, priors, waveform configuration, and software/container versions.

I’m not looking for a resampled or reweighted copy of the released posterior, and the later rerun product does not appear target-identical. If neither of these products exist a confirmation of that would also be very helpful

Thank you!

sorry I realized I didn’t link GWTC-4.0 PE release and GWTC-4 Methods §5.10
and by reproducible I’m hoping for either:

  1. Posterior samples from an independent rerun targeting the same corrected likelihood or
  2. Enough information to rerun it such as data conditioning, PSD and calibration treatment, likelihood correction, priors, waveform settings, and software/container versions

thanks again
