A second estimate of the neutrino mass scale, using the Coma Galaxy Cluster, is made. The first estimate used an approximate value of its Dark Matter mass, from weak gravitational lensing Peter D. Morley, Prediction of the neutrino mass scale using Coma galaxy cluster data, https://doi.org/10.3390/sym12061049 . In this second estimate, we use instead the size of the Coma Galaxy Cluster, using the ΛCDM Standard Cosmological Model. The underlying theory is that Dark Matter is the condensation of cosmological neutrinos. The condensation of cosmological neutrinos removes them from thermodynamic equilibrium with baryons. In their place, magnetic degrees of freedom in the Early Universe contribute to the baryon acoustic modes (removing the neutrino degrees of freedom) and are expected to change the derived value of the Planck Satellite Hubble constant H 0 , leading to the reduction or outright elimination of the Hubble Tension D. Scolnic et al., The Hubble tension in our own backyard: DESI and the nearness of the Coma Cluster, https://doi.org/10.3847/2041-8213/ada0bd . We show in the paper that the KATRIN Organization is wrong in its claimed upper bounds for the electron anti-neutrino in their Tritium T 2 molecule beta-decay experiment of 0.45 eV, because they use the wrong electron endpoint. The condensation of (cosmological) neutrinos has a critical Formula: see text neutrino mass scale dependence in the total Dark Matter mass of the Condensed Neutrino Object (CNO) P. D. Morley and D. J. Buettner, SHM of galaxies embedded within condensed neutrino matter, Int. J. Mod. Phys. D 24 (2015) 1550004. This causes a select range of Formula: see text in order to satisfy weak lensing data from Dark Matter galaxy cluster astronomical data D. J. Buettner and P. D. Morley, Neutrinos as the cold dark matter: a critical review, KATRIN and new research directions, Phys. Dark Univ. (2022) 101149.
