[AstroPy] Table Join Behavior

[Knox Long]

Can someone tell me why the join carried in the little .py script with the
data indicated, is returning this number of rows.  I would have though that
joining a table on itself would always return the same number of rows (but
this is not happening for me in the astroconda environment)

I start out with 49 rows, but end up with  97, even though I have joined
the table on itself.


Thanks
Knox

P. S. It makes no difference whether I used the Python2.7 version or the
Python3.4 version of astroconda
