Cautionary notes! Cautionary notes! The pre-launch data files currently available should be used ONLY for qualitative identification (fragmentation patterns) --- NOT for quantitative evaluations. The review processes to insure the validity and integrity of these data (files) has not yet been completed. Initial information has been included in these data files but has not yet been fully explained. This is being corrected. Work is continuing to fully define and finalize the available data.
