+This gives us an average RMS of 338 uJy. We can use this value when cleaning; we tell clean to stop when it reaches 3 times this value (or 1.014 mJy/beam):
 
 ./dac_repeat.pl --task clean --repeat map --repeat-freq rnovalmc_%f.map --repeat beam --repeat-freq rnovalmc_%f.beam --repeat out --repeat-freq rnovalmc_%f.clean cutoff=0.001014

+We can see graphic evidence of why we are using the DAC method from the output of our restor commands:
