Re: XRT/CCD bias and dark

Hi Bish,

  There is some discussion on pg 2-24 of the Blue Book (XRT section)
a PDF copy is available at:

  Steve Saar has looked at structures in the dark images and his code to
remove those is in the XRT_PREP routine.

  There is also a "grey book" on the CCD that I have only seen in  
maybe Kano has an extra copy available. I think the Blue Book text is  
the grey book.
