Thkx Bill;

Someone else provided the same page you referred me to. SBIG's web
page lists the TC-237 Offset spacing at 15.39mm measured from the center of
the KAI-11000M chip, vs.T_eS_ky6's 10.5mm. That's a difference of 4.89mm.
Using this 'correct' displacement value the Guide chip is now properly
outside the Imaging chip's boundry...joe :)
