    I had this mail exchange with Ted about two years ago :
    
    Thanks Ted,
    
    *alias* works as you described, and a COSPAR like 99000XXX with a SSN=0 works.
    You don't have to investigate further (and I have usually used a
    SkyMap prediction of other objects in the area/time frame to get a
    starting map in ObsReduce)
