Observations of IRAM04191 with uv range > 1100 kλ. The images are smoothed with a Gaussian whose full width at half maximum is approximately equal to the synthesized beam. The contours in the two images represent 3, 3.5, 4, 4.5, 5, 6, 7, 8 times the rms. Left panel: ALMA 0.89 mm data (rms 5.4e-5 Jy/beam). Right panel: ALMA 1.3 mm data (rms = 2.8e-5 Jy/beam). The white crosses represent the position of the two sources detected in the ALMA 1.3 mm data with full uv range displayed in Fig. 1.
