This has tripped me up, but I believe that the image of the mirror ball, and the
megapov "maptype 7" mapping are different. Paul Debevec explains it on
http://www.debevec.org/probes/


steradians. Also note that the mapping being used is different than the mapping
one observes in a mirrored ball -- the mapping we're using avoids the problems
of poor sampling near the backwards-facing directions around the circumference
of the image."

Cheers,
Edouard.
