Figure 6: Possible tension between and type Ia supernovae data depicted in the fitting results for the spatially flat XCDM model (similar to , except that the dark energy equation of state parameter is set free instead of being fixed at ). The SN data favor a phantom dark energy with while other data, including observational (OHD), are consistent with . The OHD used in this figure were the measurements by [28] using the differential age method, and the SN data were from [93]. The RBAO contours were found using the data in [64]. Confidence regions are , , and , respectively. This figure first appeared in [91, Figure 4].
