The data for the SDC3 Inference challenge will consist of two datasets, for two different EoR reionization models EoR1 and EoR2.
Power spectra of EoR1 + noise + SKA-Low telescope simulation for 3 (TBC) frequencies ranges, each corresponding to a redshift interval within the possible reionization history.
Power spectra of EoR2 + noise + foreground residuals + SKA-Low telescope simulation for 3 (TBC) frequencies, each corresponding to a redshift interval within the possible reionization history.
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.
