Updated Kaguya CCD Center

Sorry, I noticed that while double checking stuff in #231 Here's the relevant bit from the IK

Detector CCD Parameters
---------------------------------------------------------------------------

   The following table summarizes TC individual camera detector 
   parameters. As these data show the detectors are all line arrays.

    (*1) Center of the first pixel is defined as "1.0".


   These values are incorporated in the keywords below; pixel sizes 
   are converted to MILLIMETERS.
