    data from probe 2:  Heater state and thermocouple temperatures for        
    probe cable 1, 2, 3, and 4.                                               
                                                                              
    Diagrams of the thermocouples in the literature are labelled              
    inconsistently. It is obvious from the data that the thermocouple         
    labelled TC1 here is out on the surface, as it undergoes the greatest     
    temperature variations on all four probe data sets. Likewise the          
    thermocouple labelled TC4 is obviously the one mounted on the top of      
    the probe, deepest in the hole, as it undergoes the least temperature     
    changes and closely matches the temperatures recorded by the probe        
    sensors in the same location.  In many cases, such as in the Apollo 15    
    Preliminary Science Report, Thermocouple 1 refers to the thermocouple     
    on top of the probe, follwed by thermocouples 4, 3, and 2 in the cable    
    in order of distance from the probe.  We will use the convention
