With Erdas Imagine 9.1 we (Henk and I) corrected the files and mosaic-ed them together. Finally ! all the maps together in 1 file.
The Mr. Sid encoded img file is attached below. Irfanview (free image viewer) can display Mr. Sid encoded files.
The yellow bands in the raster file are scanner artefacts. We tried to keep them out of the composed image but on the edges that wasn't possible.
