The temperatures measured by three different methods. Temperatures measured by the three above mentioned methods, as a function of the 556 nm laser intensity (the second cooling laser). TCS 1 and TCS 2 are the measured temperatures at the lattice frequency of 395,372.29(0.01) GHz and 394,279.49(0.01) GHz. For a clear display, an offset is added to the 2nd cooling laser intensity of different methods. The inset sheet shows the temperature values. The error bar represents the 1σ uncertainty.
