September 1, 2012. Release 33.
------------------------------

This is the first release of MER1 (Opportunity) Radio Science data since 
August 2004. Because of the long gap between deliveries, these data products 
are being released as volume MER1RS_0002. The previous volume is MER1RS_0001.
The INDEX directory includes an index of the data products on this volume 
in INDEX.TAB and a cumulative index of all MER1 Radio Science data products 
in CUMINDEX.TAB.

Note that the PDS labels for ODF data files mention a document named 
NAV023-ODF-2-18_Rev3.htm. This is an old name; the current name of the
document is TRK_2_18.TXT, and it is found in the DOCUMENT directory.
