      abstract     = {The Australian, Chinese, European, Indian, and North
                      American pulsar timing array (PTA) collaborations recently
                      reported, at varying levels, evidence for the presence of a
                      nanohertz gravitational-wave background (GWB). Given that
                      each PTA made different choices in modeling their data, we
                      perform a comparison of the GWB and individual pulsar noise
                      parameters across the results reported from the PTAs that
                      constitute the International Pulsar Timing Array (IPTA). We
                      show that despite making different modeling choices, there
                      is no significant difference in the GWB parameters that are
                      measured by the different PTAs, agreeing within 1σ. The
                      pulsar noise parameters are also consistent between
                      different PTAs for the majority of the pulsars included in
                      these analyses. We bridge the differences in modeling
                      choices by adopting a standardized noise model for all
                      pulsars and PTAs, finding that under this model there is a
                      reduction in the tension in the pulsar noise parameters. As
                      part of this reanalysis, we “extended” each PTA’s data
                      set by adding extra pulsars that were not timed by that PTA.
                      Under these extensions, we find better constraints on the
                      GWB amplitude and a higher signal-to-noise ratio for the
                      Hellings–Downs correlations. These extensions serve as a
                      prelude to the benefits offered by a full combination of
                      data across all pulsars in the IPTA, i.e., the IPTA’s Data
                      Release 3, which will involve not just adding in additional
                      pulsars but also including data from all three PTAs where
                      any given pulsar is timed by more than a single PTA.},
