21.4.1. b2svd-run-simul-recon
#
Tool to run SVD-only simulation and reconstruction. No output is produced unless –root_output is used.
usage: b2svd-run-simul-recon [-h] [-n EVENTS] [--no_bkg] [--exp EXP]
[--run RUN] [--prepend_gt [GTs [GTs ...]]]
[--root_output]
Optional Arguments
- -n, --events
number of events
- --no_bkg
flag to remove beam background from simulation
- --exp
experiment number you want to simulate
- --run
run number you want to simulate
- --prepend_gt
Global Tags to be prepended
- --root_output
add this option to append the RootOuput module
21.4.2. b2svd-create-time-calib-sample
#
Tool to create the MC sample to calibrate the hit time in MC. The tool creates the rootfile to be used as input file for the caf_svd_time.py
time calibration script. For the time calibration you will need 80k events, you can produce in parallel several samples, and then input all of them to caf_svd_time.py
usage: b2svd-create-time-calib-sample [-h] [-n EVENTS] [--add_bkg] [--exp EXP]
[--run RUN]
[--prepend_gt [GTs [GTs ...]]]
--timeAlgorithm TIME_ALGORITHM
--filename OUTPUT
Optional Arguments
- -n, --events
number of events
- --add_bkg
flag to add beam background from simulation
- --exp
experiment number you want to simulate
- --run
run number you want to simulate
- --prepend_gt
Global Tags to be prepended
- --timeAlgorithm
time algorithm
- --filename
output filename
21.4.3. b2svd-import-CoGOnlyPositionError
#
SVD CoGOnly Position Error Formulas importer: json files can be found in the svd_cdb_json repository (B2SVD).
usage: b2svd-import-CoGOnlyPositionError [-h] [-j JSON]
Optional Arguments
- -j, --json
input json file
21.4.4. b2svd-create-posErrScaleFactors
#
Tool used to generate cluster position error scale factors payload, for the desired algorithm (supported: CoGOnly, OldDefault)
usage: b2svd-create-posErrScaleFactors [-h] --posAlgorithm POSITION_ALGORITHM
[-n EVENTS]
[--prepend_gt [GTs [GTs ...]]]
[--no_outliers] [--no_bkg] [--exp EXP]
[--max_pulls MAX MIN=-MAX]
[--nBins_pulls NBINS]
Optional Arguments
- --posAlgorithm
position algorithm
- -n, --events
number of events
- --prepend_gt
Global Tags to be prepended
- --no_outliers
flag to remove outliers from the computation of the scale factors
- --no_bkg
flag to remove beam background from simulation
- --exp
experiment number you want to simulate
- --max_pulls
max (min = -max) of the pulls distribution
- --nBins_pulls
number of bins of the pulls distribution
