Mars Global Surveyor: MOLA PRDRs

April 27, 2007. This release includes new data acquired by MOLA in passive radiometry mode between January 1 and November 2, 2006. All products in this release are version "D", generated using improved orbit determinations. These are the last radiometry data acquired by MOLA, as contact with the MGS spacecraft was lost on November 2, 2006.

Precision Radiometry  Data Records

PRDRs contain data acquired by the MOLA instrument acting as a passive radiometer. After the failure of the MOLA laser in June 2001, the instrument continued to gather data in this passive mode. The data files are time-ordered ASCII tables with detached PDS labels. A detailed description of this product is found in the PDS catalog description file PRDRDS.CAT, in the Catalog directory of the archive volume.
