SKA-low EoR Simulations

SKA-LOW Simulated Data for EoR with Foreground Contamination

These data correspond to a 1000h deep integration pointing with the full SKA-Low array between 106 - 196 MHz frequency range. These data were part of the SKA Science Data Challenge 3a (skasdc3a.skao.int). A full description of the dataset is available in Bonaldi et al. (2026) and their application to the SDC3a challenge is described in Bonaldi et al. (2025) arXiv:2503.11740

We publicly provide the following data products:

SKA-LOW Simulated Data for EoR inference with and without Foreground Contamination

These data contains 2D power spectra products corresponding to a 100h integration with the full SKA-Low array between 151 - 196 MHz frequency range and woth no foreground contamination (PS1, PS2 datasets) and 2D power spectra and imaging products corresponding to a 1000h integration with the full SKA-Low array between 106 - 196 MHz frequency range and with residual foreground contamination (PS3, IM1 datasets). 

These data were part of the SKA Science Data Challenge 3a (skasdc3a.skao.int). A full description of the dataset is available here and in Bonaldi et al. (2026, in preparation).
