I had a similar problem collecting radial data into cylinders.  I never
really got a good answer. In end I just ended up duplicating the first
plane in the grid and making it an "n+1" grid, coincident with the
first, so that it started and ended at the same geometric coordinates. 
This won't make the points topologically connected, but it will get rid
of the notch.
