Hi Claus, If you read the logbook - yes it can be useful - you would see a remark on page 108 book 10 "also in Daq D2 current was set to 380. Read Value is 280 == 1/10" So the field was 1/10 but is wrong in the DB i.e. it should be corrected to 281 as the other subsequent runs. Message like this should go to the list, and Betty can update the fields in the run database, but please make it more specific e.g. if you know what the correction should be e.g. change D2 current field to 281 from 380 for run 5701. Thanks for finding the problem but do also go through the logbook for runs that are being analyzed to ensure they at least at the time of the run were deemed to be good. ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov ----- Original Message ----- From: "Claus O.
