Example OM image and ds9 regions

Figure 1 shows an example of a OM image with the detected ds9 source regions- to enable the regions to be seen more clearly, only part of the image is shown.

The ds9 source regions in this image have their number in the source-list table written above them (in green if a point-like source or cyan if an extended source). Each source has one or more circles/ellipses centred on its computed coordinates. The innermost circle/ellipse identifies the source as either point-like (green) or extended (cyan).

Some features of these regions are now described:
