Left: radio map of the Mon R2 region from the NRAO VLA Sky Survey at the 20 cm wavelength. The restoring beam is a circular 45′′ Gaussian. Contours shown correspond to −3, 3, 5, 6, 8, 10, 15, 20, 30, 50, 100, 200, 300, 500, 1000, 2000, 3000, and 5000 times 0.7 mJy beam^-1, the rms noise. The 95% confidence ellipse for the gamma-ray source detected in the Mon R2 direction is plotted as provided by the two-year Fermi LAT catalog. Mon R2 is the brightest and most relevant radio source consistent with it. Right: zoom of the Mon R2 central region as observed with the VLA at the 6 cm wavelength. This high-resolution map has been selfcalibrated using the OH maser in the field (cross) and computed with pure uniform weight. Contours shown correspond to −3, 3, 4, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100, 140, and 180 times 0.7 mJy beam^-1, the rms noise. The restoring beam is shown at the panel bottom right corner as a 1.′′80 × 1.′′25 ellipse, with position angle 41°.
