Optical/NIR images (r- and z-band) of the three sources discussed in this work (30″ × 30″). Images are from Pan-STARRS in the case of PSO J0202−17 and PSJ1011−01 and from DES in the case of DES J0209−56. The solid orange circle indicates the optical position, while the dashed red circle is the uncertainty of the radio position of each object reported the RACS-low source list (∼2″).
