The cbf_simple routines such as cbf_get_detector_normal were not applying nested rotations to axis offsets. A re-release of CBFlib 0.8.1 as CBFlib 0.8.1.1 with a fix has been posted to sourceforge http://downloads.sf.net/cbflib/CBFlib-0.8.1.1.tar.gz A similar 0.9 re-release is in preparation. The SVN repository has been updated for both CBFlib and CBFlib_bleeding_edge. -- HJB ===================================================== Herbert J.
