Grid Spectra

 One of the most useful ways of displaying small SPECX does maps is called grid-spectra. This produces postage-stamp size spectra on the screen lined up in the order they appear in the map. Figure  shows what happened when I gave the following commands:

>> gr-sp
X-axis range in Velo? (km/s  ) [  215.000,  245.000] -160 -130
Y-axis range in Kelvins? [   -5.000,   20.000] -2 6
Also plot interpolated spectra? (Y/N) [N]
R.A. offset scaled from   36.000 to  -36.000
Dec. offset scaled from   24.000 to  -36.000

If the spectra does not come out right on the screen, try experimenting with set-map-size and set-map-scales. The map size determines the size of the window on the screen and the map scale determines what is in the window.
