This problem was solved by inserteing the pede values from a good run 14647 and overwritting RICH, CC and possible other values. The ped files were all in bramreco/pedestal05/pp05 - but I still lost one hour and have to redo the gtr's ---------------------------------------------------------------- Flemming Videbaek Physics Department Brookhaven National Laboratory e-mail: videbaek@bnl.gov phone: 631-344-4106 ----- Original Message ----- From: flemming videbaek To: devlist Sent: Tuesday, August 23, 2005 4:53 PM Subject: [Brahms-dev-l] pedestal runs -- 14664-14666 and 14648 There are some serious problems with the analysis off the runs given here. There were clearly just runs and inserted into the DB without any checking. Most of these runs have very few events run 18 secs,.. 89 events and so on so no wonder the data are bad. I found this since there were essentially no rich rings, and this was traced back to these pad pedestal. I have not check any other pedestals, but most likey other detectors suffers too. These make me worry that such other cases are likely to be found. Morale: Always have quality of calibratons checked before committing to DB. Otherwise some else is going to vaste their time later, and even produce wrong results. ---------------------------------------------------------------- Flemming Videbaek Physics Department Brookhaven National Laboratory e-mail: videbaek@bnl.gov phone: 631-344-4106 -------------------------------------------------------------------------------- _______________________________________________ Brahms-dev-l mailing list Brahms-dev-l@lists.bnl.gov http://lists.bnl.gov/mailman/listinfo/brahms-dev-l _______________________________________________ Brahms-dev-l mailing list Brahms-dev-l@lists.bnl.gov http://lists.bnl.gov/mailman/listinfo/brahms-dev-lReceived on Tue Aug 23 17:07:44 2005
