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.
  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.
