For field-on data we use runs 10103 and 10104.

For V0 skims we use run 10031. We use this run to get a decent sample of positrons to illuminate the "slot" sensors.

More details about the run can be found at 2019 Run Spreadsheet.

...

We list data samples publicly available at SLAC. Samples can be made available at other locations if need be.

The FEE samples are divided into top (290398 events) and bottom (318450 events) samples to allow calibration and alignment to be targeted.

Procedure

The reconstruction needs to be run over the data samples using every new detector.

...

1. Prepare a new detector using the results of a previous alignment.
   
   
2. Rerun the reconstruction over the data sets using this new detector. I suggest creating a new directory for each detector and alignment pass to keep things clean
   

   1.  For development and testing you may want to run over a single file just to test things.

      No Format
      java -server -jar hps-distribution-4.5-SNAPSHOT-bin.jar PhysicsRun2019ReReconForAlignment.lcsim -i <inputFileName> -DoutputFile=outputs/DetectorNamePassX/<outputFileName> -d <detectorName> -R 10103

   2.  For production at SLAC you can use the following for FEE 10103:  

      No Format

      for i in {000..191}; do bsub -W 4:00 -R rhel60 -o outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/logs/hps_010103.evio.00"$i".log java -server -jar hps-distribution-4.5-SNAPSHOT-bin.jar PhysicsRun2019ReReconForAlignment_multiFiles.lcsim -DinputFileList=inputs/hps_010103.evio.00"$i"_InputFileList.txt -DoutputFile=outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/hps_010103.evio.00"$i" -d HPS-PhysicsRun2019-v2-4pt5 -R 10103 -e 1000; done

      and similarly for FEE 10104: 

      No Format

      for i in {000..206}; do bsub -W 4:00 -R rhel60 -o outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/logs/hps_010104.evio.00"$i".log java -server -jar hps-distribution-4.5-SNAPSHOT-bin.jar PhysicsRun2019ReReconForAlignment_multiFiles.lcsim -DinputFileList=inputs/hps_010104.evio.00"$i"_InputFileList.txt -DoutputFile=outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/hps_010104.evio.00"$i" -d HPS-PhysicsRun2019-v2-4pt5 -R 10104 -e 1000; done

      Each set of FEE jobs normally finishes within 6 minutes, so the 600k events can be processed in slightly over 10 minutes.

   3.  For production processing of the V0 skims from run 10031: 

      No Format

      for i in {000..262}; do bsub -W 4:00 -R rhel60 -o outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/logs/hps_010031.evio.00"$i".log java -server -jar hps-distribution-4.5-SNAPSHOT-bin.jar PhysicsRun2019ReReconForAlignment_multiFiles.lcsim -DinputFileList=inputs/hps_010031.evio.00"$i"_v0skimForAlignmentInputFileList.txt -DoutputFile=outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/hps_010031.evio.00"$i"_voskimForAlignment -d HPS-PhysicsRun2019-v2-4pt5 -R 10031 -e 100; done

      
      
      

3.  The resulting root files can be concatenated using the command-line utility: 

   No Format
   hadd FEE_HPS-PhysicsRun2019-v2-4pt5_Pass0.root outputs/HPS-PhysicsRun2019-v2-4pt5_Pass0/*01010*.root

   and can be analyzed using a standard set of analysis macros to produce a series of canonical plots. Note that root version 6 or above is needed.

4.  millepede is able to accept multiple input binary files, so there is no need to concatenate them at this time.
   
   
5. Analysis proceeds as described on the SVT Detector Alignment page.
   
   
6. Once a new detector is built incorporating the new alignment proceed to the first step to iterate the procedure or test and validate a final detector.
