Contour Plots

Making contour plots with SPECX is easy. The command is contour-map. Figure  shows the result of the following commands on the map that is in Figure .

>> cont
Velo range? (km/s  ) [-160.0000,-130.0000] -142 -139
Integrated intensity? (rather than average) (Y/N) [Y]
R.A. offset scaled from   36.000 to  -36.000
Dec. offset scaled from   24.000 to  -36.000

Again, if you have trouble getting what you want, adjust the map size and scale. Also, if you do set-contour-levels you can give it specific levels by saying no to the question about `Auto-contouring required'.
