Chandra [Phys. Rev. B 77, 017101 (2008)] disagrees with the coexistence of a pseudocubic structure with a long-range tendency for cubic symmetry and tetragonal in a short-range order for the Pb1-xCaxTiO3 (PCT) system obtained by the polymeric precursor method (PPM), as proposed in our original paper [Phys. Rev. B 75, 144111 (2007)]. However, we did not show the Rietveld results for the samples in this paper. The Rietveld refinement results shown clearly the coexistence of the tetragonal-cubic phases for the PCT synthesized by PPM instead of the tetragonal-orthorhombic structures as suggested by Chandra [Phys. Rev. B 77, 017101 (2008)].
