The combined inelastic neutron scattering data from ARCS for poled PMN-30PT single crystal is at 300K and for unpoled crystal the data were collected at 300K and at 488K. The incident neutron energy for both poled and unpoled crystals was 25 meV . To obtain a significant four-dimensional Q-E volume, the crystal was rotated with steps of 0.5 degree in the beam. All individual angles were combined using HORACE software package (https://pace-neutrons.github.io/Horace/unstable/user_guide/Getting_started.html) to generate these sqw files. The file labeled PMN_PT_poled_new.sqw is for poled crystal and files labeled PMN_PT_300K.sqw and PMN_PT_488K.sqw are for unpoled crystal at 300K and 488K respectively.
