DOOUTPUT
Type: Adverb (Logical: <= 0 is false, > 0 is true)
Use:  Instructs tasks to write some particular kind of output
      file.  This adverb is used (instead of DOCAT) when the
      specified output file will not be required in many cases.
Null value:  false (-1).
Tasks:
   AGAUS......Fits 1-dimensional Gaussians to absorption-line spectra.
              DOOUTPUT controls initial choice of output images.
   BLANK......blanks out selected, e.g. non-signal, portions of an
              image.  DOOUTPUT controls writing an image of the average
              of the blanked pixels.
   CORER......Calculates correlator statistics and flags bad ones.
              DOOUTPUT controls the writing of a flagged data set.
   EVAUV......Subtracts & divides a model into UV data, does statistics
              On results.  DOOUTPUT controls the saving of the
              subtracted and divided data sets.
   HUINT......Make RGB image from images of intensity & hue, like
              TVHUEINT.  DOOUTPUT controls the writing of an output RGB
              image and/or step wedge.
   IMFIT......Fits Gaussians to portions of an image.  DOOUTPUT controls
              the writing of a residual image.
   IMLIN......Fits and removes continuum emission from cube.  DOOUTPUT
              controls the writing of images of the fit parameters.
   JMFIT......Fits Gaussians to portions of an image.  DOOUTPUT controls
              the writing of a residual image.
   LOCIT......Fits antenna locations from SN-table data.  DOOUTPUT
              controls whether previous solutions are included.
   RFLAG......Flags data set based on time and freq rms in fringe
              visibilities.  DOOUTPUT controls the writing of a file
              with channel-dependent weights.
   RMFIT......Fits 1-dimensional polarization spectrum to Q/U cube.
              DOOUTPUT controls initial choice of output images.
   RSPEC......Plots and prints spectrum of rms of a cube.  DOOUTPUT
              controls the writing of an image cube of signal/noise.
   SDLSF......Least squares fit to channels and subtracts from SD uv
              data.  DOOUTPUT controls thw writing of a continuum data
              set found by the fit.
   SERCH......Finds line signals in transposed data cube.  DOOUTPUT
              controls the writing of a signal/noise hyper cube.
   TVHUI......Make TV image from images of intensity, hue, saturation.
              DOOUTPUT controls the writing of an RGB image cube and/o
              step wedge.
   TVRGB......Make TV image from images of true color (RGB) images.
              DOOUTPUT controls the writing of a PostScript image file.
   UVLSD......Least squares fit to channels and divides the uv data..
              DOOUTPUT controls the writing of the fit continuum data
              set.
   UVLSF......Least squares fit to channels and subtracts from uv data.
              DOOUTPUT controls the writing of the fit continuum data
              set.
   XBASL......Fits and subtracts nth-order baselines from cube (x
              axis).  DOOUTPUT controls the writing of images of the
              fit parameters and uncertainties.
   XGAUS......Fits 1-dimensional Gaussians to images: restartable.
              DOOUTPUT controls initial choice of output images.
   XTRAN......Create an image with transformed coordinates.  DOOUTPUT
              controls if and how an output image is written.
   ZAMAN......Fits 1-dimensional Zeeman model to absorption-line data.
              DOOUTPUT controls initial choice of output images.
   ZEMAN......Fits 1-dimensional Zeeman model to data.
              DOOUTPUT controls initial choice of output images.
