Here is a followup on Flemmings notification on some selected runs. Peter and I have been working today with the latest MRS DSTs /brahms/data05/data/dst/MRS. The following lists the different settings and corresponding files that we found to be bad in one way or another or simply differing from the other files in that directory (such as having trigger 6 or not): 90 degrees 350A : 5693, 5694, 5696 has a bad mass2 vs p performance (bending down) 5696 also has very few good tracks 90 degrees 350B : After 5729 the spectrometer was moved back!!!!!! 90 degrees 1000B 1 - outer TOFW slats missing : Before 5895 spectrometer was moved back!!!!!! 5901 and 5902 have bad matching cuts For run 5931 and run 5932 there are no TPM2 tracks!!!! 90 degrees 1000B 2 - outer TOFW slats ok : 5940 has bad matching cuts 5962, 5963, 5965, 5971, 5972, 5973, 5974 have bad matching cuts 5983 seems to have reversed polarity when plotting theta vs p 45 degrees 700B : 53XX don't have trigger 6 while 55XX have it 40 degrees 1000B : 5572 is according to the run log a zero field run, i.e. only D1 @ 1/3 B 35 degrees 700B : 5388, 5394, 5398, 5399 have no trigger 6 5436 had an IoServer crash and thus no data Flemming Videbaek wrote: > I have found a couple of small issues in the 90 deg data sets > > > > a) the B350 run 5734 has the D5 pushed back by 50 cm and the mdst5734 > ought to go to a different directory in order not to > > be merged with the 5712-5721 runs. > > > > b) The low gain BB tubes runs 5693,94 and 96 seem all have a different > t0, so they are not useful even after the > > vertex calibrations that was done.
