North is up, West to the right. Cross-hairs denote cluster center.
The box in the chart is proportional to the effective area
of the cluster candidate. If the entire box graphic is not
seen (or is missing completely) then cluster size exceeds chart field of view. Each chart
shows a 8 x 8 arcminute area. Some charts span multiple CCD frames.
In those cases different frames are scaled to adjust for zeropoint shifts.
Some regions around bright stars have been replaced by sky level signal
to prepare the image for object detection.
