K-T In that case, I think we will need to use ra/decl of these sources, (our scheme has always been that the location of object drives partitioning for all its sources), refMatch is the only exception. This will complicate partitioner. I captured that requirement on trac at: https://dev.lsstcorp.org/trac/wiki/db/Qserv/Partitioning Serge - please keep that in mind when improving/redesigning partitioner.
