Hi I just looked at the elog for 12315; there it is already noted in the elog that settings and CDEV do not correspond. SO this is no surprise, if the DB still have the wrong field values. Morale: check the elog. It may in fact contain valuable information flemming -------------------------------------------- Flemming Videbaek Physics Department Bldg 510-D Brookhaven National Laboratory Upton, NY11973 phone: 631-344-4106 cell: 631-681-1596 fax: 631-344-1334 e-mail: videbaek @ bnl gov ----- Original Message ----- From: "Flemming Videbaek" <videbaek_at_bnl.gov> To: "Bekele, Selemon" <bekeleku_at_ku.edu>; "devlist" <brahms-dev-l_at_lists.bnl.gov> Sent: Saturday, February 03, 2007 3:13 PM Subject: Re: [Brahms-dev-l] [Brahms-l] RICH Calibration in CuCu > Hi Selemom, > > This indeed look peculiar; I can see by looking at individual files that the 12434 is the problem. > Since the radius is determined from the hit patterns on the RICH, and momentum in fact can be determined from the radius when not > saturated, it indicates that the Field was not the proper value > (but lower) for these runs.
