SD plotted vs TS ₁ and TS ₂ for case of NS + 2 SR measurements without constraints on TS. The global minimum SD for an assumed known T1 = 1200 ms is achieved with a fixed TS = TS₁ = TS₂ = 910 ms (arrow A). Note there is a local minimum corresponding to TS₁ = 1090, with very long TS₂ (arrow B) which is effectively 1 SR measurement and 2 non-saturated anchor images.
