Simulations of ALMA+ACA observationsperformed with CASA and using the ArTéMiS+SPIRE 350 μm image (André et al. 2016) as input model. Panel a: input model: ArTéMiS 350 μm map in units of Jy/ALMA-beam. Panel b: simulated ALMA+ACA image using the same set of baselines (i.e., u–v coverage) as the real data. While extended (>37′′) emission is filtered out, we note that interferometric-filtering effects do not generate spurious sub-structures within the filament.
