Tim Grey's most recent "Ask Tim Grey eNewsletter" is on the subject of
bracketing shots in taking a panorama.

In it, he says "Once you've captured the set of exposures for the
first frame, rotate the camera to the next frame, overlapping by about
20% or so...".

Some may feel that a 20% overlap is not sufficient, but I doubt if
anyone would suggest that the instructions say to pan the camera.

yet that's exactly what's done.
