We achieved a $5 \\sigma$ \\ion{H}{i} column density sensitivity of $10^{19}~\\mathrm{cm}^{-2}$ over a spectral channel width of $8~\\mathrm{km \\, s}^{-1}$ for emission filling the $180'' \\times 88''$ synthesised beam. The corresponding \\ion{H}{i} mass sensitivity is $1.2 \\times 10^{5}~\\mathrm{M}_{\\odot}$, assuming a distance of $1.9~\\mathrm{Mpc}$.
