PURPOSE       : (1) To put Schoenberg's catalogue into computer readable form.  
                (2) To combine Schoenberg's catalogue with Barnard's, for ease 
                 of comparison.
                (3) To provide J2000 coordinates for all entries.

OTHER SOURCES : My construction of Schoenberg's list was entirely dependant on 
                "A Master List of Nonstellar Optical Astronomical Objects", by
                Robert S. Dixon and George Sonneborn (1980), Ohio State Univ- 
                ersity Press. One cannot exclude the possibility that some of  
                the apparent typos, that I have identified, crept in here. 

                My work is based on printed lists. Finder charts are certainly
                desirable for accurate identification. Schoenberg's paper does
                provide charts, by my understanding. Examination of these would 
                help to resolve some discrepant positions.
