• G0Analysis Release 2.00: Paul King; 2005/05/06, 11:30.

  This is the baseline release for the new software development for the G0 Backward angle run. No changes have been made since release 1.04.

• G0Analysis Release 1.04: Paul King; 2005/01/07, 17:50

  This release was the analysis version used for the second replay of the G0 forward angle data. This release contains the new YO TDC analysis routines to calculate and store in the G0 database the run-averages helicity averaged time and helicity correlated time differences for the different YO sources. It also now will store the NA buddy Figure of Merit and errors.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 1.03: Paul King; 2004/12/22, 14:30

  This release includes the merged code from branch release G0Analysis_0_31_01_e. This now contains the FrancoAmerican analysis routines. This version also has the updated linear regression routines to allow regression corrections on each of the particle ID cuts.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.21: Paul King; 2003/07/11, 17:30

  The principle changes are: inclusion of the 120 Hz analysis routines; normaization of the beam position and charge monitor offsets by the beam scaler clock; bug fixes for the database filling routines for the Fastbus rate tables and the slow control tables; inclusion of the "10 sigma yeild cuts" for the calulation of detector yeilds and asymmetries; inclusion of Guilliaume's new deadtime correction routine for the French detectors; and the database filling routines were modified slightly to support the "10 sigma yeild cuts".

  The detailed changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.18: Paul King; 2003/06/06, 16:15

  The principle bug fixes are to: the NA deadtime correction routines used to extract the "tartan table" rates from the database records, the "beam trip cut", and the regression analysis routines. The NA deadtime correction routine bug resulted in the zeroing of the deadtime corrections in the previous full pass of the analysis. The fix to the "beam trip cut" is so that runs which do not have the beam on at the beginning of the run are handled properly. The fix to the regression analysis corrected several errors which corrupted the slopes calculated in the analyser. There were some minor changes in the database access routines for filling and extracting data.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.15: Paul King; 2003/05/29, 09:45.

  Incorporates several bug fixes found during the first stage of the second pass analysis.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.14: Paul King; 2003/05/21, 19:39.

  This is the production release for the "second pass" analysis. It includes the deadtime corrections and the six parameter regression analysis.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.13: Paul King; 2003/03/20, 10:35.

  Interim release containg a few small changes; the modifications to include K. Nakahara's 6 parameter regression are expected shortly, so this release will freeze the condition before that is added.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.12: Paul King; 2003/01/30 15:35.

  This release includes all of the modifications made since the beginning of the G0 commissioning run. This version is identical to what was being used on the machines g0ana, cdaql1, and cdaql2; you should use this version to compare to the online analysis results.

  The other changes made in this version are discussed in the file README/ReleaseHistory.txt.

• G0Analysis Release 0.07: Paul King; 2002/05/21 11:30:00.

  Changes since release 0.06:

  • Updated the NA scaler map file to include all three crates.
  • Enabled the code to ignore a new Fastbus decoding word.
  • Various changes to clean up the code:
    • Did the speed test on the offline code with Wolfgang. Optimized the code at various places. Modified NA ProcessEvent so that it no longer does the dividing of the time bin width (especially the 0th timebin with 6.5 ns width). Dividing the yield at this step creates round-off error.
    • Cleaned up vdetector/tscintillator/octant routines. Provided the "cleaners" for the root objects in NA, French, Beam, Asymmetry and Helicity classes to avoid potential segv.
    • Studied the NA deadtime correction a little more. Implement Wolfgang's changes. Also changed the convergence limit to %5 of statistical error, based on a simulation, to reduce the number of the required iterations.
    • Set the flag to turn off the histogramming for NA, French, Beam, Asymmetry and Helicity classes. The command line flag: --offhists BeNaFrAsYi. (The order of the objects is not important.) Also create TDirectories for these histograms according to the --offhists flag and sort the histograms into them. The dirs are: "NATOF", "FrenchTOF", "BeamHists", "AsymHists", "YieldHists".
    • Multi-run replay (-r firstrun:lastrun) fixed and tested. Fixed some loop counters and misc flags for the purpose of the multi-run replay.
    • Now no error messages for the size of TS crate when doing\ fastbus run replay.
  • Entered several new Fastbus channel mapping files.
  • Changed the name of the real-time executable from "g0online" to "g0realtime".
  • Consolidated all of the file opening operations into a new function, to aid readability of the source code.
  • Created a function ExitGracefully. This function closes files, etc. in case of problems.
  • The main G0Analysis routine and the main G0Realtime routine have been modified to use the Fastbus configuration file "Setup.05-06-02.dat" by default if the -s flag is not used on the command line.
  • More code clean-up:
    • Removed the chain test and system test remainders in the code to avoid confusion.
    • Removed the flag to switch off TS data analysis. We will always analyze the TS crate data.
    • Moved the yield normalization against the beam charge after the event cut on the beam charge. Also reset some quartet and event counters before the run-by-run analysis for proper multi-run replay.
    • Removed ConstructHists(), FillHists() and ClearHists() methods in NA, French, Beam, Yield, Asym classes. Defined a new G0Hists class that handles the histogramming of all the physical classes, except for Fastbus.
    • By default, no histogramming during the on/offline replay. Added --onhists flag on the command line to turn it on, if desired. The histograms are defined in the G0Hists class according to the list Paul sent out (FastBus hists are left out).
    • Added a Sigma function (as inline function.h in sample code) routine to to make the calculation of standard deviation in different classes a little more compact.

• G0Analysis Release 0.06: Paul King; 2002/03/28 11:20:00.

  Several major changes since release 0.03. See the file "README/ReleaseHistory.txt" in the distribution for details. See the file "README/Installation" in the distribution for a guide to compiling the analysis software.

• G0Analysis Release 0.03: Paul King; 2002/02/18 17:39:00.

  Added ".keepme" files to the directories: "Analysis/dictionary", "G0ROOT/dictionary", "G0ROOT/scripts", "GUI/dictionary", "bin", and "lib". These files will ensure that the directory is created when the source code is checked out using the "-r" or "-P" options. Also, this release history was implemented.

  Other changes since release 0.02:

  • spayde on Fri Feb 15 11:40:10 EST 2002
    Modified Files: .G0Setup.bash .G0Setup.csh
  • pking on Mon Feb 18 15:51:26 EST 2002
    Added administrative files to control logging of the tagging utilities.

• G0Analysis Release 0.02: Paul King; 2002/02/11 17:39:38.

  Corrected several minor compilation problems so that G0Analysis now compiles on the JLab Linux machines (ifarml1, etc.) and on the JLab Solaris machines (jlabs2, ifarms1, etc.).
