1.1 mm continuum map for MACS J1149 made with natural weighting. The image has an rms of 71 μJy beam^-1 and has not been corrected by the primary beam sensitivity for visualization purposes. The color scale and black curve are the same as in Fig. 1. Squares show the positions of the sources with S/N ≥ 5. In the small box bottom left corner we show the synthesized beam of 1.̋2 × 1.̋08 and position angle of −43.̊46. The critical curves (i.g. where magnification is infinite) for a source at z = 2 given by the model GLAFICv3 (Kawamata et al. 2016) are shown in green.
