May 12, 2017. MESSENGER Release 16 includes two tutorials: the GRS Anti-Coincidence Shield Tutorial and the NS Description of Analysis and Modeling Tasks, found in the Document directories of the GRS CDR/RDR and NS CDR/DDR volumes, respectively, and also linked from this web page, under Related Information below. No new or revised GRS or NS data products are in this release.

 See the GRS ERRATA.TXT and NS ERRATA.TXT in each data set's top-level directory for details about previous releases.

GRS and NS are the Gamma Ray Spectrometer and Neutron Spectrometer instruments on MESSENGER. The data sets are produced by the GRS/NS Science Team at Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland.
