After calibrating the predictions of the Effective Field Theory of Large-Scale Structure against several sets of simulations, as well as implementing a new method to assert the scale cut of the theory without the use of any simulation, we analyze the Full Shape of the BOSS Correlation Function. Imposing a prior from Big Bang Nucleosynthesis on the baryon density, we are able to measure all the parameters in ACDM + massive neutrinos in normal hierarchy, except for the total neutrino mass, which is just bounded. When combining the BOSS Full Shape with the Baryon Acoustic Oscillation measurements from BOSS, 6DF/MGS and eBOSS, we determine the present day Hubble constant, H0, the present day matter fraction, SZm, the amplitude of the primordial power spectrum, As, and the tilt of the primordial power spectrum, ns, to 1.4%, 4.5%, 23.5% and 7.6% precision, respectively, at 68%-confidence level, finding H0 = 68.19 +/- 0.99 (km/s)/Mpc, SZm = 0.309 +/- 0.014, ln(1010As) = 3.12+0.21 -0.26 and ns = 0.963+0.062 -0.085, and we bound the total neutrino mass to 0.87 eV at 95%-confidence level. These constraints are fully consistent with Planck results and the ones obtained from BOSS power spectrum analysis. In particular, we find no tension in H0 or o8 with Planck measurements, finding consistency at 1.2u and 0.6u, respectively.
