Serge, Daniel Please see: https://jira.lsstcorp.org/browse/DM-854 Are you touching the part of the code that is responsible for that? If not, I am happy to try fixing it, any hints where to look are very welcome. I would like to have it fixed before giving Qserv to google cloud team, as it prevents us from running near neighbor query. thanks Jacek ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the QSERV-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1
