Comments:

Step 1
  Read the cyan`demo-single-imager.uvt` uv table in an internal buffer.
Step 2
  Check current state of the variables that control the imaging.
Steps 3-5
  Select the robust weighting threshold (step 4) from the result of the magenta`UV_STAT` command (step 3) and recheck the current state of the variables that control the imaging (step 5).
Steps 6-8
  Image and plot the dirty beam and image.
Steps 9-12
  Try a smaller size of the map as the default imaged field-of-view looked too large from previous plots.
Steps 13
  Make a Post-Script file from the dirty image.
Steps 14-15
  Write dirty image and beam in `demo.lmv` and `demo.beam` files for deconvolution in a future [rgb]1,0,0IMAGER session. These steps are optional as you may directly proceed to the deconvolution stage without writing the files.
