Hi all, I am not sure how to direct this question, so I go for the broadest possible group. Run 4264 (which was taken from roughly 0430 to 0530 Sat. GMT, or 1130 Friday night to 0030 Sat. morning BNLNST) has, according to the shift report and the run index, D2 turned off. This is great, as it should allow me to 'tune' the FFS geometry. I have looked at some of the data, now, and I find that if I use the run data base and the SetMagnetField() in BrModuleMatchTrack, I obtain a field value (and here I must confess that I do not remember, and did not check whether the message there returns the value of GetField() or GetBdl()) of -0.106. This raises the question (at least to me): How do the magnet settings get written into the run data base? Is there some monitor that measures the current, or is it the current setting? Also, do we have, at present, any method of checking the fields in the magnets? I realize, of course, that this is not a big problem since 0.1 is not too big (only a few percent of the fields we actually use), but I am a bit curious as to how this could come about. Any info is much appreciated. And you should all be happy to know that there are tracks in all TPCs for 4264...at least the first sequence. Have a nice Saturday, I hope the weather were you are is as beautiful as it is here in Birkerød. -Ian
