The most sensitive image of NVSS 2146+82 is derived from our BnC configuration data at 1.4 GHz which has a resolution of 13'' (FWHM). Figure 2 shows logarithmic contours of the total intensity in the region around the source in this image; the rms noise is 20 µJy per CLEAN beam area. A gray scale representation of the same image showing the filamentary structure of the lobes is given in Figure 3. Figure 4 shows the inner region of this image contoured to lower levels using an initially linear contour interval.
Figure 2: Contour plot of the new 1.4 GHz total intensity data for the field at 13'' (FWHM) resolution. Contours are shown at -1, 1, 2,4, 8, 16, 32 and 64 times 100 µ Jy per CLEAN beam area.
Figure 3: Gray scale image at 13'' (FWHM) resolution using a nonlinear transfer function to emphasize the lower brightness levels. The jet and strong filaments in the lobes can be seen.
