Comments:
- Step 1
- Read the
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
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
IMAGER
session. These steps are optional as you may directly proceed to the
deconvolution stage without writing the files.
