Displaying Image Fields

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

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