The 95% lower limit on the distance to individual SMBHBs with ﹩{ \mathcal M }={10}^{9}\,{M}_{\odot }﹩ and ﹩{f}_{\mathrm{gw}}=8\,\mathrm{nHz}﹩ as a function of sky position based on an analysis of the 11 yr data set, plotted in equatorial coordinates using the Mollweide projection. The stars indicate the positions of pulsars in our array, and the diamonds indicate the positions of known SMBHB candidates or galaxy clusters that may contain SMBHBs. At our most sensitive sky location, we place a limit of dL > 120 Mpc for SMBHBs with ﹩{ \mathcal M }={10}^{9}\,{M}_{\odot }﹩, and ﹩{d}_{L}\gt 5.5\,\mathrm{Gpc}﹩ for SMBHBs with ﹩{ \mathcal M }={10}^{10}\,{M}_{\odot }﹩.
