    If these files are what they appear to be, it's very interesting indeed.
    There are only a very few TLEs available for this cis-lunar satellite (see
    below);  a dense data set such as you seem to have found could show much
    about lunar-solar perturbations and other effects in the middle heavens.
    
    Is there an orbital mechanic in the SeeSat audience who can convert the XYZs
    into TLEs?
    (I've grabbed the files from GSFC and can mail them as a zip file if
    necessary.)
    
    Now if someone could only find the Vela orbital data....
