ORDER
Type: Adverb   (Real)
Use:  ORDER usually is used to express the order of a polynomial in
      fitting a spectral baseline.
Null value:  0
      Means fit a zero-order polynomial (DC).
Tasks:
   AGAUS.........Fits 1-dimensional Gaussians to absorption-line spectra
   BSCOR.........Combines two beam-switched images.  ORDER controls the
                 removal of a baseline from each row of each image.
   BSGRD.........Task to image beam-switched single-dish data.  ORDER
                 controls the removal of a baseline from each row of
                 each image.
   ELFIT.........Plots/fits selected contents of SN, TY, SY, PC or CL
                 files.  ORDER is the polynomial order fit to the data
                 in antenna zenith angle, elevation, hour angle, etc.
   FIXFR.........Modifies UV data set making all frequencies increase or
                 decrease.
   FLGIT.........Flags data based on the rms of the spectrum
   IMLIN.........Fits and removes continuum emission from image cube
   SDLSF.........Removes continuum from single-dish line data, flags bad
                 samples, writes also a continuum data set.
   SLFIT.........Task to fit gaussians to slice data.
   SOUSP.........Fits source spectral index from SU table or adverbs.
                 ORDER selects spectral index plus optionally various
                 degrees of spectral curvature.
   UVLIN.........Fits and removes continuum visibility spectrum, also
                 can flag.
   UVLSD.........Least squares fit to channels and divides the uv data.
   UVLSF.........Removes continuum from UV data, flags bad samples,
                 writes also a continuum data set.
   UVMLN.........Edits data based on the rms of the spectrum.
   XBASL.........Fits and subtracts nth-order baselines from cube (x
                 axis)
   XGAUS.........Fits 1-dimensional Gaussians to images: restartable.
   XTRAN.........Create an image with transformed coordinates.  ORDER is
                 the number of parameters to be fit (3 or 6).
"Verbs":
   BDF2AIPS......Read EVLA ASDM/BDF data into AIPS.  ORDER is a logical
                 to prevent/allow reordering of IFs.
