    We report a new improved procedure for experimental data fitting in photorefractive fringe-locked running hologram experiments. From this fitting we compute the diffusion length LD, the Debye screening length l s, and the quantum efficiency for photo-excitation of charge carriers Φ, with a lower degree of uncertainty than reported in previous publications. The procedure was successfully tried on an undoped B 12TiO20 (BTO) crystal and led to LD = 0.16νm, ls = 0.038νm, and Φ = 0.33, in good agreement with the already available information on this sample. The effectively applied electric field coefficient in the experiment was also estimated.
