That must be some developper sense of humour. To the best of my knowledge, the best documentation of the CTable2 format is the driver source code: https://github.com/OSGeo/gdal/blob/master/gdal/frmts/raw/ctable2dataset.cpp Basically there is a 160-byte header, followed by the longitude and latitude offsets, interleaved, and with south-to-north line ordering.
