# Validation parameters Qv, Qs, Qe are defined in the range of 0 to 1, with 0 indicating poorest reliability and higher value indicating a more reliable site
Qv measures the agreement of the inner-sphere bond valence summation with the oxidation state of Mg2+ (+2)
Qs measures the geometrical symmetry of the ligands distribution around the Mg2+ required for octahedral geometry
Qe measures the agreement of the isotropic atomic displacement (B) factor and occupancy of the Mg2+ compared to those of all atoms in its environment
