+DESCRIPTION
+
+The \fITABOVERLAY\fR task is used to overlay a catalog of positions on 
+the image display.  The input catalog file is assumed to be an ascii
+table of the form (index,ra,dec) however the \fIracol\fR, \fIdeccol\fR and
+\fIlabcol\fR parameters can be used to select columns from tables containing
+more information.  Markers will be drawn using the color specified by the
+\fImkcolor\fR parameter.
+
+.ih
+EXAMPLES
+1. Query for catalog positions of NGC188 and extract the (numbered) position
+columns to the file 'ngc188.pos'.  Then display an image of the field and
+overlay the catalog positions.
+
+.nf
+  votools> getcat gsc2.3 ngc188 size=0.1 output="ngc188.xml"
+  votools> votpos ngc188.xml number+ out="ngc188.pos"
+  votools> dss ngc188
+  votools> taboverlay ngc188 ngc188.pos
