Posterior probabilities ﹩P\left({O}_{i}| x\right)﹩ for the most likely host (solid bars) and all other candidates (open bars) with ﹩P\left({O}_{i}| x\right)\gt {P}_{\mathrm{secure}}=0.95﹩, as a function of prior set (green=conservative; black=adopted). With ﹩{P}_{\mathrm{secure}}=0.95﹩ as the probability for a secure association, there are currently nine FRBs satisfying this criterion using the adopted prior set. The nonsecure hosts occur for a variety of reasons as described in the text.
