notes

Generally a copy of the onlinePE configuration, but with the upper Mchirp prior bound extended from 200 to 300 Msun L-only analysis is fully capable of explaninig HL posterior, the H-only analysis contains literally no signal information. Posteriors from HL (as well as L-only analysis) consistent with the onlinePE analysis Due to the extended prior, the ROQ likelihood was not applicable, and the standard GravitationalWaveTransient was used The analysis also was done with the coherence-test active, only the HL analysis is uploaded to GraceDB
