Abstract:

A companion paper [1] presented RIFT results for parameter inference for GW170729 with higher modes, computed using a variety of waveform models including numerical relativity, showing these results are in good agreement with one another. The RIFT analyses with HM are in modest tension with corresponding results computed with another parameter inference code (LALInference) when using similar settings. In this document, we describe the RIFT results, and investigations to assess their reliability. After exhaustive testing of our HM analyses specifically, particularly via extensive tests with SEOBNRv4HM, we know of no concrete reason to doubt the RIFT HM results presented in that study.
