Figure 4
Fit parameters ΔT (left axis) and Δρ (right axis) as well as $[\tilde{\chi}^{2}]$ (left axis) along the temperature ramp of T₁. The fits are calculated using ΔT = 3 K and from fitting ΔS(Q, T) with the ESRF reference signals as seen in Fig. 3

. ΔT_Meas. and the expected values Δρ_1atm are shown for comparison. Δρ_1atm is calculated based on tabulated water density data at a pressure of 1 atm (Lemmon, 2010

) and the measured temperature change, ΔT_Meas..
