== Displaying Image Fields ==

There are several ways to display fields covered by a set of images.  This example illustrates the combination of the [wiki:Imbox imbox] command with a [wiki:For_loop for loop] to display fields of fits files that have not been imported to a DVO database.

|| region ra dec size         || (set the display region to be centered roughly on where you expect your images to lie) || 
||list mylist -x "ls *.fits"  ||      (this makes a list, called "mylist", which contains the names of the fits files in the current directory) || 
||??                          ||              (this displays all the variables in current memory.  You can check this to determine the number of elements in "mylist") || 
||for i 0 n                   ||          (replace n with 1 less than the number of elements in mylist)    || 
||imbox $mylist:$i            ||        (remember: $ precedes non vector variables when called)            || 
||end                         ||     ||
