CMETHOD
Type:  Adverb  (String*4)
Use:   To select the method used to compute the fringe visibilities of
       the source model.
       'DFT ' uses the direct Fourier transform, which is the most
              accurate.
       'GRID' does a gridded-FFT interpolation model computation.
       '    ' allows the program to use the fastest method, which is
              usually DFT at the beginning of a Clean and GRID later
              when there are mode Clean components to subtract
Null value:
       ' '  => task chooses
Tasks:
   CALIB.......Determines the calibration to be applied to a uv data set
               given a model of the source.
   IMAGR.......Images and Cleans uv data.
   MX..........Images and Cleans uv data.
   SCMAP.......Images, cleans, and self-cals a uv data set iteratively.
   UVSUB.......Subtracts/divides a model from/into a uv data base.
   WFCLN.......Images and Cleans uv data.
