Displaying Map Data

Several techniques are useful. First, typing

$\gt\!\gt$ gr-sp

will display a set of postage-stamp spectra on the page. You provide a number of parameters defining the plot.

Second, use

$\gt\!\gt$ cont

to obtain a contour plot.

Or, better yet (provided you are working on a Sun workstation or something similar), type

$\gt\!\gt$ gray

to obtain a gray-scale plot. This can be turned into various colour schemes, with a number of options. I suggest you experiment; using the interactive mode is a good way to do this - type `h' within the plot to see the options available - or in non-interactive mode use the command

$\gt\!\gt$ set-gray

Finally, either using s-p-d h and sending one of the above commands, or typing see-map, will save the image to a file (e.g. specx_pgplot.ps) suitable for output to the printer.
