As some of you have heard I am doing a very preliminary reconstruction of the pp data as there are being collected to
maintain check's on quality and estimates of rates etc.
The reconstruction is based on
-- Bjoerns' shiftreco.C script (slightly modified)
-- Tuned geometry for T1,T2 that matches H1 and zero-filed runs.
-- TPC run with a fixed Vdrift.
-- H1,H2 ,TOFW, TD1 and mrst0 calibrations done with end of dA data; committed to DB
mainly as run 8650 (a non-existing run between dA and pp) , but with some added calibration for
run 8925 due to the jump seen in H1, H2.
-- Rich pressure (ref index) was adjusted to match the max ring radius.
-- The version of bratmain was 'my own' with output files, and histograms in
the directory /brahms/data07/scratch/bm/seq + merged + log
Note the use of scratch to indicate this is not an official pass or anything like this, and is subject
to change without notice (but will probably stay around until after the coll meeting)
In general only histograms are merged, and in addition several groups
of run histograms were merged using the mergehist.C scripts in same dir.
You are of course welcome to inspect, use any of these files for further checking and analysis
