Dear Dr. Daniel L. Wang,
Thank you for telling me about the spatial indexing that will be used by Qserv.
I have enclosed the reference article for the Q3C spatial index concept:
Koposov, S., & Bartunov, O. 2006, Astronomical Data Analysis Software and Systems XV, 351, 735;
Q3C, Quad Tree Cube -- The new Sky-indexing Concept for Huge Astronomical Catalogues and its
Realization for Main Astronomical Queries (Cone Search and Xmatch) in Open Source Database
