NAME
nedoverlay -- Overlay NED objects in the image display

clutter the display.
.le

Mark radio sources on the display?
.le
.ls xrays = yes
Mark X-Ray sources on the display?
.le
.ls mkcolor = 208
Marker color.

DESCRIPTION
The \fINEDOVERLAY\fR task is used to overlay sources from the NED service on
the image display. 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.
If the \fIgalaxies\fR parameter is set, a small cross will be drawn at the
position of each NED galaxy using the color specified by the \fIgalcolor\fR
parameter. All other markers will be drawn and labelled using the
\fImarkcolor\fR value.

EXAMPLES
1. Display an image of m83 and overlay the NED radio sources in the field.
