Fscan
Fscan pipeline for characterizing persistent narrowband spectral artifacts in gravitational wave detector data
Installation
On Unix systems, Fscan can be installed easily using conda:
conda install -c conda-forge fscan
Or from PyPI:
pip install fscan
LALPulsar and lalframe are required for running but optional dependencies. You may either install it into the environment using
conda install -c conda-forge fscan[conda]
or install LALSuite from source.
Running Fscan
Fscan runs on LIGO site computing resources (LHO, LLO, or CIT) by accessing the frame files directly on-disk (not via NDS).
The main way to run Fscan is using the FscanDriver program on the command line together with arguments that tell Fscan how to run.
One key argument is the channel configuration file. This file contains the information needed on how the Fscan program finds and processes data on an individual channel basis. Example channel configuration files may be found here.
Example running Fscan
Run the FscanDriver <args> exectuable with appropriate arguments (see FscanDriver -h for additional details). For example at CIT:
FscanDriver --chan-opts=fscan-configuration/configuration/examples/example_ch_info.yml --SFTpath=. --create-sfts=1 --plot-output=1 --accounting-group=ligo.dev.o4.detchar.linefind.fscan --accounting-group-user=albert.einstein --analysisStart=20200229 --analysisDuration=1day --averageDuration=1day
Another example (using a configuration file)
Running from the Fscan source directory,
FscanDriver --config configuration/example.config
Be sure to edit the arguments in example.config to reflect the locations of your lalsuite and fscan installations.
