In particular, events which are contrived to be coincident (via a common pulser input) are apparently not coincident. The origin of this is not well understood but has been narrowed to some discrepancy in the clearing of the MUX card count… text/html 2013-07-08T20:03:25+00:00 Anonymous (anonymous@undisclosed.example.com) https://zzz.physics.umn.edu/!lowrad/nmm/lbcftimingtests?rev=1373313805&do=diff veto shield station correlated timing The veto shield has 4 independent DAQ stations NE,NW,SE,SW in each geographical corner of the Soudan 2 cavern at Soudan. Each station has two or three front-end electronics multiplexer (MUX) boards. The expected relative timing resolution of < 4us for our 1kHz GPS carrier, had been observed as of June 4th 2013 on only one station-mux-combination pair. The pair which showed the good timing was SE MUX 2, to SW MUX 2. The correlated timing was confirmed us… text/html 2013-06-18T23:14:23+00:00 Anonymous (anonymous@undisclosed.example.com) https://zzz.physics.umn.edu/!lowrad/nmm/lrtproceedings?rev=1371597263&do=diff We have a total of 4 pages for the paper.
