    6       <DESCRIPTION>VOTable description of PSPS table ObjectThin</DESCRIPTION>
     6      <DESCRIPTION>Contains the positional information for objects in a number of coordinate systems.  The position of an object in the stack is used as the basis for coordinates when available, with the mean position from the single epoch data when it is not.  The right ascension and declination for both the stack and single epoch mean is provided.  The number of detections in each filter from single epoch data is listed, along with which filters the object has a stack detection.  References: Szalay, A. S., Gray, J., Fekete, G., et al. 2007, arXiv:cs/0701164.</DESCRIPTION>
