(A) Low energy fits of the $B_{1g}$ response of SP208 using a damped Lorentzian for the QEP and an odd in frequency third-order polynomial for the low energy part of the broad peak (Supporting Information). (B) Temperature dependence of the inverse of the two contributions to the nematic susceptibility, $A_1^{-1}$ and $A_2^{-1}$ for SP208 (blue dots) and MK (red triangle). The dashed line is a linear fit of $A_1^{-1}$ between $T_S$ and 150 K. (C) Temperature dependence of the QEP line width ${\mathrm{\Gamma }}_1$. The dashed line is a linear fit between $T_S$ and 150 K.
