I am forwarding this on behalf of Ian. Flemming. ---------------------------------------------------------------- Flemming Videbaek Physics Department Brookhaven National Laboratory From: Ian Bearden <bearden@nbi.dk> Date: 26. februar 2004 14:44:06 MET To: brahms-l@bnl.gov Subject: news from the run! Hi all, While Per did all the work on our shifts, I got to play a little bit with some of the data. I have done a number of TPC calibrations for runs between about 10100 and 10400, and today finally managed to get dsts for some runs. You can find the data either here: /brahms/data14/data/run04/auau/200/rXXXXX or here: /brahms/data08/data/run04/auau/200/rXXXXX where XXXXX= run number. I have used the "standard" scripts for local and global tracking, and am still testing the dst stuff. Today, I looked at one high field, 4 degree polarity B run (10326, to be exact) to see if things were more or less working OK. Here is a plot which shows that maybe things are OK though much remains to be checked!!!! Here is a plot of rich radius vs. momentum for tracks having a reasonable D4 momentum: -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Please note the nice deuteron signal :-) There are roughly 3400 tracks contributing. I have not yet checked to see what fraction of the data this corresponds to, but will do that soon. One final note: please feel free to play with the DSTs as they appear, but THEY ARE PRELIMINARY and are NOT to be trusted yet.
