Background-subtracted sources (Sect. 2.6). The field of Fig. 2 is shown as the true intensities of the model sources at 350 μm convolved to a 17′′ resolution (left), the background-subtracted image ℐ_λO   BS at 350 μm (middle), and the composite 3-color RGB image (500, 250, 160 μm) created using the images of the deblending shapes of each extracted source (right). For the true model intensity distribution (no background) to be more comparable to the background-subtracted image, it is shown above 5 MJy/sr. The color coding is a function of the square root of intensity in MJy/sr.
