The EXTRAS directory contains files which facilitate the use of the data on   
the disk, but which are not actually required for the use or understanding    
of those data.

                   Binary STereoLithography (STL) file containing the Gaskell
				   digital terrain model in the updated (new pole RA/DEC) 
				   Dawn Claudia coordinate system.  The STL format can 
				   be read by many Computer Aided Design software programs.

                   ASCII version of the Gaskell digital terrain model in the
                   updated Dawn Claudia coordinate system.  The file contains
				   the vertices and connectivity matrix for the digital
				   terrain model. A description of the contents follows:
				   <number of vertices>   
				   <vertex index>  <x (km)>   <y (km)>    <x (km)>    
					                    ...             
				   <vertex index>  <x (km)>   <y (km)>    <x (km)> 
				   <number of triangles>
				   <triangle index> <vertex>_0 <vertex>_1 <vertex>_2  
					                    ...             
				   <triangle index> <vertex>_0 <vertex>_1 <vertex>_2
