The observations represent the deepest single-dish HI intensity maps to date, produced from 41 repeated scans over $236\\,{\\rm deg}^2$, providing 62 hours of observational data for each of the 64 dishes before flagging. By introducing an iterative self-calibration process, the estimated thermal noise of the reconstructed maps is limited to ${\\sim}\\,1.21\\,$mK ($1.2\\,\\times$ the theoretical noise level).
