Stokes I images of the 3C 286 field, using MSMFS with N_t = 1 (top left), N_t = 2 (top right), N_t = 3 (bottom left), N_t = 4 (bottom left). The peak flux of 3C 286 is 14 Jy/beam. The axes labels are in units of arc-minutes from the pointing center and all images are shown with the same grey-scales. The residual rms near 3C 286 for these four images are 9 mJy, 1 mJy, 200 µJy and 140 µJy, and the rms measured 1 degree away from 3C 286 are 1 mJy, 200 µJy , 85 µJy and 80 µJy. The thermal-noise limit for this dataset was 70 µJy.
