thumbnail Fig. 1

Radio images of Cyg OB2 #9. For each of the 11 observations, we show the C-band (6 cm) image at the top, and the L-band image (20 cm) at the bottom. The observation date is shown in each title. Each image shows a small region centred on Cyg OB2 #9. The contour levels are listed at the top of each figure. They are shown as solid/dashed lines for positive/negative values. The levels were chosen so that the lowest positive level is at about 2 × the root-mean-square (rms) level. The highest level is below the peak flux value of Cyg OB2 #9. The synthesized beam is shown by the filled ellipse in the bottom left corner of each figure. The size of the image can be different for different figures (due to the changing configuration of the EVLA).
