Hi,
	I have just put an image on my problems Web Page at 

http://www.ast.cam.ac.uk/~apo/docs/probs.html

Showing an image from our latest Loral CCD (with the PPtF backside 
treatment) and exhibiting a number of long horizontallish streaks.  These 
weren't readily visible by eye inspection when I installed the chip in the 
dewar. 

I am supposed to be transporting this to the Telescope around 10th May - I hope 
at least to be able to Flat field the marks out which will be okay provided 
they arent affecting other device performance parameters...

Have a look if you have the time - any comments as usual are welcome...

Cheers
Paddy
