The local2globalRF script is transforming the tracks reconstructed by the DTF software and the PattRec software (mixed with mutomca_mixer) from the local reference frame of the DT detector to the global reference frame (same as MC simulations, centered in the cask).
The output file contains the tree muCastorMC tree with a CastorSkinHits branch having a similar structure of the OpenCMT Castor simulation file.
The required environment is describe in the guide.
The local2globalRF is available in baltig:
git clone https://baltig.infn.it/muontomography/python-muotom-utils.git |
under the folder src.
The only command line option required by the application is the path of a configuration file. The configuration file is a INI-file containing the following sections and parameters:
[geom] theta0 = 0 theta1 = 180 dist = 3535 shift = 96.5 corrM_DT1 = 0 corrQ_DT1 = 0 corrM_SL1 = 0 corrQ_SL1 = 0 [IO] is_MC = 0 chunk = 0 main_file = mixed_data.root output_file = SkinHits.root |
Section geom
| Variable | Type | Description |
|---|---|---|
theta0 | float | DET0 rotation (deg) in the global reference frame |
theta1 | float | DET1 rotation (deg) in the global reference frame |
dist | float | Distance (mm) between the center of the two DT detectors |
shift | float | Vertical shift (mm) between the center of the DT detectors and the cask center |
corrM_DT1 | float | Misalignment correction factor for angular coefficients of tracks reconstructed by DT1 with respect to DT0 |
corrQ_DT1 | float | Misalignment correction factor for intercept of tracks reconstructed by DT1 with respect to DT0 |
corrQ_SL1 | float | Misalignment correction factor for angular coefficients of tracks reconstructed by SL1 with respect to SL0 |
corrQ_SL1 | float | Misalignment correction factor for intercept of tracks reconstructed by SL1 with respect to SL0 |
Section IO
| Variable | Type | Description |
|---|---|---|
| is_MC | bool | 1 for MC simulations, 1 for data |
| chunk | int | (only for MC) Number of subsets in which dataset is divided to be processed (to avoid combination of repeated evNumber) |
| main_file | string | Input file (mixed data) with path |
output_file | string | Output file with path |
The application can be run with
python local2globalRF.py --conf=<path of the configuration file> |
