Detailed Description

This class represents an annotation for a circular (in position coordinates) region specified in an ascii region file as proposed in CAS-2285. It is specified by its center position and radius. <author>Dave Mehringer</author>

Review Status

Date Reviewed:: yyyy/mm/dd

Etymology

Holds the specification of an annotation of a circular region as specified in ASCII format. Specified by center position and radius.

Synopsis

This class represents an annotation of a circular region in coordinate space specified by center and radius. Note that this represents a world coordinate region, even if the input radius is in pixels. If the direction coordinate does not have square pixels, then AnnEllipse should be used instead.

Simplified constructor.

all frequencies are used (these can be set after construction). xcenter and ycenter must be in the same frame as the csys direction coordinate. is a region (not just an annotation), although this value can be changed after construction.
