MESSENGER PDS3 to PDS4 Migration Status: Complete

For more information about RSS derived data products, see the: OCC Product SIS • SHADR Product SIS • SHBDR Product SIS

Note: The product SIS files were created for PDS3, but they are still applicable to the data after the PDS4 migration.

The MESSENGER RSS derived product collection consists of products derived from radio science measurements made using the MESSENGER spacecraft and Earth-based stations of the NASA Deep Space Network (DSN). The collection includes three type of products: 1) High-resolution spherical harmonic models of Mercury's gravity field derived from raw radio tracking data; 2) Measurements of Mercury's radius at several locations around the planet derived from radio occultations; and 3) Spherical harmonic models of Mercury's surface shape from both Mercury Laser Altimeter (MLA) data and occultation data. Code refers to the product type abbreviation used in the file name.

Code	Product type	Description	Storage Format

SHADR	Spherical Harmonics ASCII	This product type contains spherical harmonic models of several different degrees and order for the Mercury gravity field and planet's surface shape expressed in a set of ASCII tables.	ASCII Table
SHBDR	Spherical Harmonics Binary	The product type contains spherical harmonic models of several different degrees and order for the Mercury gravity field expressed in a set of binary tables.	Binary Table
