Examples of Processing Problems:

Brighter CCD in the image is not represented in the exposure map:
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:
EPIC PN image (netscape)	EPIC PN image with sources overlaid (netscape)
Bright outer CCDs in PN, probably corrupt data:
EPIC PN image (netscape)
Central CCD in M2 is shifted
EPIC M2 image (netscape)	EPIC M2 image (ds9)
Apparently inverted image (outside of FOV is brighter):
EPIC PN image (netscape)
Only central window observed (special observing mode but called 'PrimeFullWindow'):
EPIC M2 image (netscape)
Dimmer central CCD despite the same GTIs for all CCDs - possibly failed special observing mode
EPIC PN image (netscape)
No counts in the image despite good exposure time:
EPIC PN image (netscape)
