DOEBAR
Type: Adverb (Real)
Use:  DOEBAR > 0 requests display of the uncertainties in the data;
      false (<= 0) suppresses the display.
Tasks:
  ALVAR.....Plots the Allan Variance statistic of a UV data set.
  CAPLT.....Plots closure amplitude and model from CC file.
  CLPLT.....Plots closure phase and model from CC file.
  PRTUV.....Prints contents of a visibility (UV) data set
            DOEBAR > 0 causes the weights to be replaced by an error
            estimate ( = 1 / sqrt(weight) ).
  RM........Task to calculate rotation measure and magnetic field.
            DOEBAR selects normal or error image on output.
  VPLOT.....Plots uv data and model from CC file
