1. Makes <strong>class</strong> quiet.<br />
2. Turn off nearly all output messages.<br />
3. Open an image window (necessary to plot 2D images).<br />
4. Change the orientation to portrait.<br />
5. Title in short format.<br />
6. Set arcsecond units.<br />
7. Open the file.<br />
8. Build an index according to offsets.<br />
9. Build a 2D array.<br />
10. Display the whole index.<br />
11. Define a polygon interactively to set spectral windows. By default the polygon is stored in<br />
a file window-1.pol.<br />
12. Substract a 1st order polynom to all records.<br />
13. Display the result.<br />
14. Change the polygon filename (to avoid overwritting it next time).
