## Typical imaging session

           1 read uv demo
           2 input uv_map
           3 uv_stat weight
           4 let weight_mode "UN"
           5 let uv_cell[2] 0.1
           6 input uv_map
           7 uv_map
           8 show beam
           9 show dirty
          10 let map_size 256
          11 uv_map
          12 show beam
          13 show dirty
          14 go wedge
          15 hardcopy demo-dirty
          16 write dirty demo
          17 write beam demo

Comments:

Step 1
  Read the `demo.uvt` table in an internal buffer.
Step 2
  Check current state of the variables that control the imaging.
Steps 3-6
  Select the robust weight mode (step 4) and threshold (step 5) from the result of the `UV_STAT` command (step 3) and recheck the current state of the variables that control the imaging (step 6).
Steps 7-9
  Image and plot the dirty beam and image.
Steps 10-13
  Tries a larger size of the map as the default imaged field-of-view looked too small from previous plots.
Steps 14-15
  Make a Post-Script file from the dirty image.
Steps 16-17
  Write dirty image and beam in `demo.lmv` and `demo.beam` files for deconvolution in a future MAPPING session. These steps are optional as you may directly proceed to the deconvolution stage without writing the files.
