Notes: Exp4 supersedes Exp3 after running with more live points to attempt to solidify the RAVEN FAR estimate Exp4 has been labelled as the Illustrative result, though there is still railing chirp mass and luminosity distance, as the prior strongly dominates this signal's inference. Labelled HIGH_PROFILE due to coincident SWIFT trigger Event with a very low significance (455/yr)
