Notes. ( † )Each channel of each ViCTORIA field has its own uv coverage and therefore its own dirty beam. As in Serra et al. (2023), we adopted a fixed restoring beam for all channels and all fields to simplify the analysis of the H I mosaics. The parameters of these fixed restoring beams are shown in this table. They were chosen as the best match to the ensemble of all dirty beams of the first 135 ViCTORIA fields observed.
( † †)Median noise level per channel across the mosaic. The actual noise varies as a function of position and frequency.
