In the data files containing posterior samples, the masses are given directly in the source frame, accounting for redshift by dividing the measured "redshifted" masses by (1+z). Here, we have taken the redshift z=0.0099 to be constant across all samples, equal to the geocentric redshift of NGC 4993 at the time of the event, based on the MUSE/VLT measurement.
