Apertures used for flux measurements. The map shows the integrated value of the [CII] spectrum (moment 0) for the lower resolution combination. The white ellipses represent: The QSO, the DSFG, and the clumps (C1, C2, C3, C4, S0, and S1). The white apertures are used to extract the [CII] 1D spectra and to measure the continuum of the clumps. The continuum of the QSO and DSFG are estimated using the green ellipses representing the 2D Gaussian fit of the continuum. The synthesized beam is shown in the bottom-left as a white filled ellipse. North is up and east is to the left.
