ΩΛ=0.62+0.24−0.35. This measurement is completely independent of, and in agreement with, the local distance ladder measurements of H0. We explore more general cosmological models combining TDSL with other probes, illustrating its power to break degeneracies inherent to other methods. The joint constraints from TDSL and Planck are H0 = 69.2+1.4−2.2 km s−1Mpc−1, ΩΛ=0.70+0.01−0.01 and Ωk=0.003+0.004−0.006 in open ΛCDM and H0 =79.0+4.4−4.2 km s−1Mpc−1, Ωde=0.77+0.02−0.03 and w=−1.38+0.14−0.16 in flat wCDM. In combination with Planck and baryon acoustic oscillation data, when relaxing the constraints on the numbers of relativistic species we find Neff = 3.34+0.21−0.21 in NeffΛCDM and when relaxing the total mass of neutrinos we find Σmν ≤ 0.182 eV in mνΛCDM. Finally, in an open wCDM in combination with Planck and cosmic microwave background lensing, we find H0 =77.9+5.0−4.2 km s−1Mpc−1, Ωde=0.77+0.03−0.03, Ωk=−0.003+0.004−0.004 and w=−1.37+0.18−0.23.
