We measure the expansion rate of recent Universe and calibration scale baryon acoustic oscillation (BAO) from low-redshift data. BAO relies on scale, i.e., sound horizon at end drag epoch $r_d$, which often imposes a prior cosmic microwave background (CMB) measurement Planck satellite. In order to make really independent measurements $H_0$, we leave $r_d$ completely free use data sets combined ...
