The RIXS intensity maps with energy window chosen to isolate the excitons a and magnons/double-magnons b as a function of in-plane momentum transfer H measured in the (H0L) scattering plane. All the measurements were taken at T = 190 K with linear horizontal π polarization of the incident x-rays at the resonant energy of 853.4 eV for excitons. The same data are provided as linecuts in Supplementary Figs. 9 and 10.
