Comparison of physical parameters in XVXGC catalog and other X-ray cluster catalogs. The grey dashed lines show a 1:1 relation. The best-fitting linear function is shown in a black line, with the 1σ error shown in the grey region. The parameter values of the best-fitting linear model and K-S test parameters are shown in Table 4. In the first panel, after removing two outliers at the lower-right part, a second best-fitting model is overlaid as the blue dotted line together with the cyan shade for its 1σ error. In the second panel, the second best-fitting model is also overlaid when the outlier at the upper-left part is removed.
