GMVA maps of J1130+3815, J0700+1709, J1044+8054, and J0748+2400 (left panel), shown together with the respective radial amplitude distributions (right panel) and uv-coverages (inset in the right panel) of the respective visibility datasets. The contouring of images is made at levels, with σ_rms representing the off-source rms noise in the residual image. The lowest contour in the maps, L = 21.2 mJy beam⁻¹, 15.8 mJy beam⁻¹, 18.8 mJy beam⁻¹, and 26.6 mJy beam⁻¹, respectively. A total of 174 contour maps of 162 unique sources imaged at 3 mm in this survey are available in Appendix A.
