Top panel: posterior distributions of ΩK in three different ΩK cases with 500 mock FRBs data. The derived ΩK value are clearly well consistent with the assumed values. The bottom two panels show the ability of our method when the sample includes 1000 and 2000 FRBs. The blue and green histograms show the results without and with the systematic uncertainty, respectively.
