Rosetta Draft Data Set Area This directory tree contains Rosetta data sets that have been released to the community by ESA, but that are NOT CERTIFED and are still considered to be in active development with respect to PDS archiving requirements. These should be treated as early draft versions of the final data sets. Because they are in active development, the labels and data may change without notice and without the usual adherence to PDS versioning and change documentation standards. New data will be posted as soon as it is available from the PSA. Superseded data will be removed from this website without comment. Users are advised to check the MD5 checksums supplied when downloading and to track the last modification dates of the files they are using. Once a dataset posted here has been reviewed and certified by the PDS for archiving, it will be removed from this site and a stable draft posted to the Rosetta mission archive page: (http://pdssbn.astro.umd.edu/data_sb/missions/rosetta/index.shtml). Subdirectories are provided for each orbiter- or lander-mounted instrument returning data destined for the archive. The instrument directory will be empty if there are currently no public versions of data sets in development available for the corresponding instrument.
