This directory contains 42 second samples of Mariner 10 position information  
from the Mercury 1 and 3 encounters. The information provided is from the     
Mariner 10 Supplemental Experimenter Data Records (SEDR). The files are IEEE  
binary tables in MSB byte order.                                              
                                                                              
Additional position information is provided for the Mercury 1 encounter in    
the 42 second MAG data (/DATA/MAG/MERCURYI/AVERAGE/MAG_M1_ENC_42SEC_MO.TAB).

Mercury encounters, or the software needed to manipulate them please contact
