Stokes I emission from the W43_MM1 clump indicated by the colorscale in Jy ﹩{\mathrm{beam}}^{-1}﹩. Overlaid are the sources extracted as ellipses, in black, representing the deconvolved sized obtained from the Gaussian fits. With an rms noise of ﹩\sigma =0.41﹩ mJy ﹩{\mathrm{beam}}^{-1}﹩, the dynamic range of the self-calibrated image is 1220.
