Jansky Very Large Array (VLA) observations over an area of $\\sim$60 arcmin$^2$ taken as part of the CO Luminosity Density at High Redshift (COLDz) survey. COLDz \"blindly\" selects galaxies based on their cold gas content through CO($J$=1$\\to$0) emission at $z$$\\sim$2-3 and CO($J$=2$\\to$1) at $z$$\\sim$5-7 down to a CO luminosity limit of log($L'_{\\rm CO}$/K km s$^{-1}$ pc$^2$)$\\simeq$9.5.
