Examples of Non-obvious Extended Sources


In case of doubt, use the source comments 'Possibly extended' for the center of the suspected extended source.
 

 

Point-like bright extended source (galaxy cluster):

[000524-comp] [000524-comp]
  EPIC composite image (netscape)  EPIC composite image (ds9)
 

 

Point-source in combination with a very diffuse filament:

[000514-comp] [000514-comp]
EPIC composite image (netscape) EPIC composite image (ds9)
 

 

Faint and diffuse patch:

[000618-PN] [000618-PN]
EPIC PN image (netscape) EPIC PN image with contours overlaid (ds9)
 

 

Very faint and diffuse small patch towards the edge:

[000351-M2] [000351-M2]
EPIC M2 image (netscape) EPIC M2 image with contours overlaid (ds9)
 

 

Many small sources with very diffuse material associated with them:

EPIC PN image (netscape) EPIC PN image with contours overlaid (ds9)
 

 

Small extended source off-center:
