Transmission power spectrum P_j (solid line) for the real sample Q1700+642, calculated by estimator eq. (41), and the power spectrum ﹩P^{t}_{j}﹩ (dashed line) calculated by eq. (46). The dot‐dashed line represents the power spectrum normalized by the traditional method. The dotted line is the power spectrum by eq. (46) for the phase‐randomized field. The error bar is given by the maximum and minimum of 20 realizations. The scale j corresponds to ﹩2^{11-j}( 34) ﹩ h⁻¹ kpc.
