INTRODUCTION
=============================================================================

The DATA directory within the MESSENGER Radio Science Reduced Data Record
(RDR) volume contains four types of products and their associated
detached PDS label files.:
1. The Spherical Harmonics ASCII Data Record (SHADR) gravity product
   (GGMES_*V<nn>_SHA.TAB).
2. The Spherical Harmonics Binary Data Record (SHBDR) gravity product
   (GGMES_*V<nn>_SHB.DAT).
3. The Spherical Harmonics ASCII Data Record (SHADR) shape product
   (GTMES_*V<nn>_SHA.TAB).
4. The Occultation Summary (OCCSUM) product (MESS_RS_OCC_V<nn>.CSV).

<nn> is a version number range 01..99.

All RDR products are accompanied by full, detached PDS labels.

Each of these products is described in its corresponding Software Interface
Specification (SIS) document contained in the DOCUMENT directory of the
same archive volume. The SIS documents have attached PDS labels and are:
   DOCUMENT/SHADR.TXT
   DOCUMENT/SHBDR.TXT
   DOCUMENT/OCCSUM.TXT
