The data for the SDC3 Inference challenge will consist of two datasets, for two different EoR reionization models EoR1 and EoR2. 

All power spectra will be cylindrical (2D) power spectra. Dataset 1 will allow testing of the intrinsic performance of the EoR inference codes in the absence of any bias in the data. Dataset 2 will investigate the robustness of the approaches against foreground residuals.
