Examples of Processing Problems:


 

Brighter CCD in the image is not represented in the exposure map:

[000446-M1] [000446-M1]
 EPIC M1 image (netscape)  EPIC M1 image with sources overlaid (netscape): the edge due to the difference in brightness causes many spurious detections  
 
 

Fainter quadrant of CCDs in PN not represented in the exposure map:

[000489-PN] [000489-PN]
 EPIC PN image (netscape)  EPIC PN image with sources overlaid (netscape)  
 

 

Bright outer CCDs in PN, probably corrupt data:

[000580-PN]
 EPIC PN image (netscape)   
 

 

Central CCD in M2 is shifted

[000921-M2] [000921-M2]
 EPIC M2 image (netscape)  EPIC M2 image (ds9)  
 

 

Apparently inverted image (outside of FOV is brighter):

[001338-PN]
 EPIC PN image (netscape)   
 

 

Only central window observed (special observing mode but called 'PrimeFullWindow'):

[001349-M2]
 EPIC M2 image (netscape)   
 

 

Dimmer central CCD despite the same GTIs for all CCDs - possibly failed special observing mode

[001160-M2]
 EPIC PN image (netscape)   
 

 

No counts in the image despite good exposure time:

[000326-PN]
 EPIC PN image (netscape)
