ATCA 9 GHz image of the 2019 April 16 observation (MJD 58589), with two radio sources identified as RK1 and RK2 in Carotenuto et al. (2021). Contours start at three times the rms (∼25 μJy beam⁻¹). The position of MAXI J1348–630 is marked with a magenta cross. Top: Original RK2 emission produced by two point-sources whose fit positions are marked with a yellow and black cross. We identify the yellow cross with the true position of RK2, at an angular distance of ∼1.1 arcsec from the core, while the black cross is an additional component (RK3) or core emission from MAXI J1348–630. Center: Residual image after the image-plane subtraction of the two above-mentioned point-sources, showing only Gaussian-like noise at the position of MAXI J1348–630. Bottom: Residual image after the image-plane subtraction of a single point-source with the location free to vary, and marked with a blue cross, showing residuals above the three sigma level near MAXI J1348–630.
