You can get full ilnformation, including image circle size of a specific
lens, and the image circle required to fit a specific format at:

http://www.bhphotovideo.com/

go to SEARCH and 

type in LARGE FORMAT

 then go to LARGE FORMAT CONTENTS

then:  LARGE FORMAT LENSES

NOTE: The original Q was about 45mm Apo-Grandagon, NOT the 45XL. The XL has
a significantly larger image circle to accomodate the 6x12 format and some
movements.
