GMRT image of the HAT-P-11 field at 150 MHz on July 16, 2009. The green ellipse in the lower-left corner shows the half-power beam width. The contour levels given at the top of the image are in units of Jy beam^-1 and are defined as mean + rms × (n), where values of n are given in the brackets. Thus, the first, second, and third contours correspond to 1.5 × 1.05 mJy, 2.1 × 1.05 mJy, 3.0 × 1.05 mJy, etc. Negative contours appear as dashed lines.
