NOISE
Type:  Adverb  (array(64))
Use:   Gives the noise estimate for up to 64 fields in the *TESS
       imaging tasks.  In UV flagging, used as a noise level cutoff as
       a function of up to 64 IFs.  Used elsewhere when a large array
       is needed.
Null value:
       None
Tasks:
   FIXBX.......Converts a BOXFILE to another for input to IMAGR.  NOISE
               is misused to convey the old RASHIFT values.
   FLATN.......Re-grid multiple fields into one image incl sensitivity.
               NOISE gives the relative error for each pointing.
   LTESS.......Makes mosaic images by linear combination.
   OMFIT.......Fits sources and, optionally, a self-cal model to uv
               data.  NOISE gives the a priori noise and 2 cutoffs.
   RFLAG.......Flags data set based on time and freq rms in fringe
               visibilities.  NOISE is an IF-dependent cutoff for time
               rms values.
   SOUSP.......Fits source spectral index from SU table or adverbs.
               NOISE gives the expected noise for up to 64 frequencies.
   STESS.......Finds sensitivity in mosaicing.
   UTESS.......Deconvolves polarization images by maximizing emptiness.
   VTESS.......Deconvolves sets of images by the Maximum Entropy Method.
   WTMOD.......Modifies weights in a UV data set.  NOISE provides the
               weight scale for each antenna.
