Updated THcHallCSpectrometer.cxx

In method TrackCalc get the proper THcDCTrack array index
from the golden track by using method GetTrkNum
for use in the THcDC method
SetFocalPlaneBestTrack.

When creating the THaTrack array in THcDC::CoarseTrack
the array index between THaTrack and THcDCTrack arrays
 match. The THaTrack is also associated with the THcDCTrack
array index with the call SetTrkNum(index+1)

When selecting best track by lowest chi-squared the
THaTrack are sorted from lowest to highest chi-squared
The code made a mistake in the index used in
 SetFocalPlaneBestTrack. It used the array index of the
THaTrack which is now not in sync with the THcDCTrack.
Fixed problem by using the THaTrack method GetTrkNum
which gets the proper THcDCTrack array index.


This did NOT effect reconstructed target variables or
physics variables. It only effected the focal plane
varaiables that were selected as the "best" or "golden"
to be used for the tree for dc.x_fp , dc.xp_fp,
dc.y_fp , dc.yp_fp and for the residuals.

hcana - Hall C ROOT/C++ analyzer

hcana is an under-development tool to analyze data from the HMS, SHMS and SOS spectrometers in Hall C at JLab. It is being developed to replace the historical Hall C analyzer, ENGINE, which was written in Fortran. hcana will be the package used to analyze Hall C date in the 12 GeV era. hcana is being written in C++, using the CERN ROOT framework. hcana is an extension to the Hall A analyzer, PODD.

NOTE: In the process of retrieving the hcana source code, a copy of the Hall A PODD package will be downloaded. The version of PODD included has been slightly modified for use with hcana. For an official version of PODD, see the ROOT/C++ Analyzer for Hall A page.

Downloading

Instructions for downloading hcana can be found in the Hall C Wiki.

Compiling

hcana may be compiled with either make or scons. Switching between these two build systems make require some cleanup of dependency files, binary files and other autogenerated files.

Before compiling, type source setup.sh or source setup.csh depending on whether your shell is bash or csh.

Compiling with scons

scons

Additional SCons features

To do the equivalent of "make clean", do scons -c To compile with debug capabilities, do scons debug=1 To compile the standalone codes the are part of podd, do scons standalone=1 To run cppcheck (if installed) on the Hall C src diretory, do scons cppcheck=1

Compiling with CMake (experimental)

Do the usual CMake setup

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$HOME/local/hcana ..
make -jN install

Here $HOME/local/hcana is an example installation destination; modify as appropriate. You will need to add the bin and lib[64] sub-directories under the installation prefix to your environment:

export PATH=$HOME/local/hcana/bin:$PATH
export LD_LIBRARY_PATH=$HOME/local/hcana/lib64:$LD_LIBRARY_PATH

On macOS, the library directory is usually simply lib instead of lib64.

CMake does not yet support the SCons features "standalone" and "cppcheck".

The default CMake build type is "RelWithDebInfo", i.e. debug symbols are included in the binaries, but the code is optimized, which may cause the debugger to act in a confusing way on occasion. To build a non-optimized debug version, run CMake as follows:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$HOME/local/hcana-dbg ..
make -jN install

Compiling with make (deprecated)

make [-jN]

Running

Basic instructions on how to run hcana are in the Hall C Wiki.
