The temperature dependence of the dielectric susceptibility chi(g) is recalculated by making the elastic modulus K temperature dependent for the chiral smectic C phase in HDOBAMBC. For this calculation, the experimental data for the spontaneous polarization P-S, tilt angle theta and the helical pitch rho are used from literature close to the AC* transition in HDOBAMBC. The temperature dependences of the wave vector of the helical modulation q, the elastic free energy F and the critical electric field E-C are also calculated by using the temperature dependent elastic modulus K for the chiral smectic C phase close to the AC* transition in this ferroelectric liquid crystal.
