SIMULATE /NOISE

          IMAGER\SIMULATE /NOISE NoiseValue [BandWidth]

      Define the expected final point source noise (in Jy), for the Model  chan-
    nel  spacing  or  the  specified  BandWidth (in MHz) if present.  This noise
    level is used to rescale weights accordingly, and generate appropriate scat-
    ter for the simulated data in the SIMULATE NOISE step.
