Notes on Overlapping Geometries in y2014

Picture Below shows a 10 cm z-slice of the inner region of STAR.

The RED cylinder inside of IBMO is APTS.  This is a part of the pixel support tube. 

Current radius of IBMO is too small if marked as ONLY.  It masks off the APTS in PSTM.  Moving the radius back to its original value allows us to flag IBMO as only.
