The same environment provided by the guide is suitable.
The source code for the SLFitter is stored in Baltig.
Since the source code of the SLFitter can be downloaded only by the authorized developers, credentials for Baltig are necessary. The simplest way is using RSA keys, the public key must be uploaded into Baltig and the private key must be saved into ${HOME}/.ssh/id_rsa |
Once git client has been correctly configured the commands are:
git clone git@baltig.infn.it:muontomography/SLFitter.git cd SLFitter |
The commands to build the code are:
cmake3 <path-to-source> make |
<path-to-source> is the path to the CMakeLists.txt file in SLFitter directory, e.g.: /home/centos/SLFitter |
The executable is found in the directory run/
The SLFitter application performs the reconstruction of tracks from CMS Super-Layers (SL) hits produced with the castor-simulator software, see The OpenCMT Castor Simulator.
All the input parameters needed to run the code must be set in a dedicated configuration file config.ini. A template of this file can be found in the utils/ directory and must be copied in the run/ directory. Now you can modify the config.ini file in your run/ directory.
General information
| Variable | Type | Description |
|---|---|---|
| runNumber | int | number of the castor-simulator dataset to be analyzed |
| rawDirName | string | path of the input file directory |
| rawFileName | string | name of the input file |
| outputDirName | string | path of the output file directory, e.g. ../output |
| outputFileName | string | name of the output file |
| maxEventNumber | int | maximum number of events to be read |
Execution mode:
The application can be run in three different modes (please choose only one mode at each execution)
TTree mode: fill a root TTree with the reconstructed track parameters and save them in a root output file
| Variable | Type | Description |
|---|---|---|
display | bool | set to 1 to run in Display mode, 0 otherwise |
| wait | bool | should be equal to the display variable |
| histos | bool | set to 1 to run in Histograms mode, 0 otherwise |
| ttree | bool | set to 1 to run in TTree mode, 0 otherwise |
Debugging
| Variable | Type | Description |
|---|---|---|
| debug | bool | set to 1 to dump debug messages |
Castor MC information
| Variable | Type | Description |
|---|---|---|
| is_CastorMC | bool | set to 1 for simulated datasets (0 not implemented for now) |
| use_trueDriftTimes | bool | set to 1 to use true drift times, 0 to use smeared drift times |
| det0_rot | float | same rotation angle set for det0 in MC simulation [deg] |
| det1_rot | float | same rotation angle set for det1 in MC simulation [deg] |
| det_dist | float | same distance of det0 and det1 from origin in MC simulation [cm] |
