Bayes factors for the presence of a GW signal in each pulsar’s residuals, from an analysis of the 11 yr data set with ﹩{f}_{\mathrm{gw}}=109\,\mathrm{nHz}﹩. The GW parameters were fixed to the maximum-likelihood values, as determined from a detection analysis. We concluded that this signal was primarily coming from PSR J1713+0747, for which ﹩{{ \mathcal B }}_{10}=96.2(1)﹩.
