Row data reading
The SSD row data are read from the daq files with the StSsdDaqMaker. This code is currently under review and will be soon accessible under cvs.
This maker is using the StSSDReader and SSD_Reader classes developped by Herb Ward and accessible in StDaqMaker and StDaqLib.
This maker has two main goals :
to do the conversion from a (Daq-asic,FEE channel) ordering into a (ladder, silicon strip) ordering
fill an appropriate table depending on the type of data to read
The SSD hit reconstruction is done by the StSsdPointMaker accessible from the software guide. This maker takes the ouput table of the StSsdDaqMaker, do the cluster finding and cluster matching in the wafers. The hits found are then filled in a StSsdHitCollection of StEvent.
The star note 427 contains some documentations on it. Jonathan is publishing is latest plots here
The SSD hits reconstructed are used in ITTF to build tracks in the STAR central region.
A geometry specific to the SSD has been built in Sti for this purpose and stored in StiSsd. The tuning of the tracking in the SSD is just starting.
This page gives an overview of the histograms that can be represented when running the bfc with the ssd option. Pedestal and physics features are explained.
