In UV flagging, used as a noise level cutoff as a function of up to 64 IFs. Null value: None Tasks imaging: LTESS.......Makes mosaic images by linear combination. STESS.......Finds sensitivity in mosaicing. UTESS.......Deconvolves polarization images by maximizing emptiness. VTESS.......Deconvolves sets of images by the Maximum Entropy Method. Tasks UV: RFLAG.......Flags data set based on time and freq rms in fringe visibilities. NOISE is an IF-dependent cutoff for time rms values. ----------------------------------------------------------------
