== 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                        }}} ||     ||
