If the \fIimage\fR parameter is an +object name, it's position will be resolved and a query for sources within +\fIsize\fR degrees of that position will be used. If it is an image name, +the WCS footprint of the image will be used to generate the query. + +The \fICONTOUR\fR task is used to draw the overlays and should be consulted +to adjust the overlay as desired. + +.ih +EXAMPLES +1.
