SKA-Mid Simulated HI image cubes
SKA-Mid HI simulated image cubes
These data correspond to a 2000h simulated observation of a 20 square degree area with the full SKA-Mid array between 950 - 1150 MHz frequency range. The dataset has been designed to enable HI source finding and characterization and includes truth catalogues with the HI sources injected in the simulation as well a companion radio continuum image. These data were part of the SKA Science Data Challenge 2. A full description of the dataset is available in Hartley et al. (2023), arXiv:2303.07943
Datasets of increasing size are available, as listed above. All datasets include a truth catalogue and the accompanying radio continuum image

Scoring package
To evaluate one's performance in HI source finding and characterization, the scoring module used for the SKA science data challenge 2 is available as a pip-installable Python package here. Running this package requires the truth catalogues for the datasets of interest (available above). The format of the catalogue needs to strictly follow the formatting rules adopted in SDC2 for the scoring package to work correctly.
