ORDER
Type: Adverb   (Real)
Use:  ORDER usually is used to express the order of a polynomial ofetn
      in fitting a spectral baseline.
Null value:  0
      Means fit a zero-order polynomial (DC).
Tasks:
  FLGIT.......Flags RFI from spectral UV data.
  UVLIN.......Removes continuum from UV data, flags bad samples.
  UVLSF.......Removes continuum from UV data, flags bad samples, writes
              also a continuum data set.
  SDLSF.......Removes continuum from single-dish line data, flags bad
              samples, writes also a continuum data set.
  IMLIN.......Fits and removes continuum emission from image cube
  XBASL.......Fits and subtracts nth-order baselines from cube (x axis)
