Fig. 1
Greyscale map showing the local rms noise measured in the mosaic image. The
greyscale shows the rms noise from 0.5σavg to
2σavg, where
σavg = 3.0 mJy beam-1 is the approximate
rms in the mosaic centre. The contours are plotted at
. Peaks in the local noise coincide
with the locations of bright sources.
