the images have the same pitch and roll values - assuming you used a
tripod and pano head. You should start by aligning the images
roughly by hand using the panorama editor window. Pay particular
attention to the two that don't quite overlap, and align those as
accurately as you can.
Assign control points, and for the initial optimization, check the
link pitch and roll boxes in the advanced features of the optimizer
tab. Optimize y,r,p on all images except uncheck yaw on the two non
overlapping images. (Also include lens parameter b for
optimization). Then uncheck the link pitch and roll boxes. Uncheck
y,p,r for the two non overlapping images to anchor them both, and
optimize y,p,r on all the other images.
After, optimization and generating the final panorama image, you can
if necessary fine tune the alignment of the two halves of the
panorama in Photoshop and clone over the gap. If you take care not
to crop the image, you can input the edited image to PTGui with lens
parameters set to the projection and fov of the panorama image to
correct verticals and a wavy horizon. This might be necessary if the
vertical rotation axis of the panorama head was not quite vertical.
