In Pantheon+ and DES-SN5YR, with Ωm = 0.3 ± 0.01, does the preference for dynamical dark energy persist after the exclusion of each of the six BAO tracer groups?
Individual public-manifest question. The method and limitations are in its record.

In Pantheon+ and DES-SN5YR, with Ωm = 0.3 ± 0.01, does the preference for dynamical dark energy persist after the exclusion of each of the six BAO tracer groups?
The group exclusions produced unequal responses in the fit. The comparison established neither independence of the preference from every group nor exclusive dependence on any one group.
