L1551 NE from the 336 GHz ALMA observation (contours + colour scale). The black crosses in the image indicate the peaks of the disk emission of the two sources in the 24 GHz image to show the approximate positions of the central stars. The jet axes of the two components from Reipurth et al. (2002) are shown by the dotted white lines. We note that there is a displacement between the peaks of the ALMA 336 GHz image and the 24 GHz image due to proper motion of the source between the epochs (Oct. 2019 and Jan. 2021) which was not corrected for in the image. The contour levels are −3, 25, 50, 75, 100, 125, 150, and 175 × σ_rms, where σ_rms is the root-mean-square noise of the image. The synthesised beam for the image is shown in the bottom left corner. The values for the synthesised beam and σ_rms are given in Table 4.
