Phase-referenced images of J0006 observed at the K-band after a few CLEAN iterations. (a) The image without troposphere delay corrections has a noise rms of 2.7 mJy beam⁻¹ and (b) the image with troposphere delay corrections has noise rms of 1.3 mJy beam⁻¹. The interferometric beam (ellipse) is displayed on the bottom-left corner of each image. Contours represent 1%, 2%, 4%, 8%, 16%, 32%, and 64% of the peak intensity at each image.
