Hello, I committed to DB calibrations for BBC for 62 GeV Cu+Cu run. I had to changed the reference tubes for both left and right arrays, because otherwise I could not get a correct vertex distribution. The main problem I could see so far: as Kris noticed in the e-log, http://brahms-web.brahms.bnl.gov/cgi-bin/elog.pl?nb=2005&action=view&page=173 there is a typical change in the tdcs by ~50 channels. More than this, the adc gains seem also to have moved by ~50 channels. Changing the reference tubes provides a way to check... So, if anybody is looking at these data - please write if you see any strange problems related to the vertex. For reference, the run numbers are: 13674, 13686, 13760, 13770, 13789, 13821. Thank you!
