2025-11-07 Model-independent late-universe measurements of H0 and ΩK with the PAge-improved inverse distance ladder doi:10.57760/sciencedb.31252 en This dataset comprises all fitted MCMC posterior chains from the paper "Model-independent late-universe measurements of H0 and ΩK with the PAge-improved inverse distance ladder." We employ two global and cosmic age-based parameterizations, PAge and MAPAge, to perform model-independent measurements of the Hubble constant H0 and ΩK by utilizing the inverse distance ladder (IDL)，with comparative analysis also conducted under the ΛCDM framework. To construct the PAge-improved IDL, we utilize the strong gravitational lensing (SGL), cosmic chronometers (CC), and gamma ray bursts (GRB) data to calibrate the latest DESI DR2 baryon acoustic oscillation data and DESY5 type Ia supernova data.
