README.TXT FILE FOR PLOT TRANSFER DIRECTORY

This directory contains binary HPGL, GIF, and color postscript
format plot files for the Central West Antarctica aeromagnetic
data.  See the web site for index maps and more information.
The HPGL plot files are in RTL format and will plot on 36-inch
plotters such as the HP750.  The color postscripts files are
page sized, and will plot on any color postscript printer.

These plot files have been compressed using the "gzip" public-domain
utility.  Before plotting these files you will need to uncompress them.
Information on gzip is available at:

 http://www.maths.lancs.ac.uk/~smithdm1/GNU/GNUWeb/gzip.html
   (unix and PC DOS versions)

 http://www.winzip.com/
   (PC windows version)
