        I believe you are correct about VEC2TLE.  I haven't the foggiest
about Vladimir's vectors (if he sees this, maybe he can let us know?).  If
anyone observes M-34 using these keps, I'd appreciate a note as to their
accuracy (or lack thereof).  A learning experience....

        And my thanks, Neil, for your comments!
