We present an independent estimate of the power-law index of the temperature-density relation for the intergalactic medium at intermediate redshifts. The automatic program for analyzing Ly-alpha forest in the quasars spectra using Voigt profile fitting is developed. The proposed method can be easily extended to study large samples of archival quasar spectral data in an automatic regime.
