Notes. Values of H0 (in km s−1 Mpc−1) from different sets of SNe Ia and calibrators. Note that for the same calibrator sets, differences in the uncertainty stem mostly from the number of objects in the Hubble flow. SNooPy pre v2.7 is the one used in U24/F25. *In this case only 52 out of the 55 calibrators could be matched with the given set of fit SNe Ia. +In this case only 32 out of the 35 calibrators could be matched with the given set of fit SNe Ia.
