Contour images of the JVLA field around the three JVLA targets in the D and CnB configuration as observed at the X band that were not detected. The size is 3′ × 3′ for the two first images taken in D configuration and 2.6′ × 2.6′ for the last one observed in CnB configuration. Contour levels are 3, 5, 10, 15, 20, 30, 50, and 100 times the image rms, which is listed in Table 9. The right ascension and declination of the phase center for the observation for each target is listed in Table 3.
