The full name of this option for the EsoRex configuration file is **sinfoni.north\_south\_test.dev\_tol** \[default = *20.0*\]. Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command. ## SEE ALSO The full documentation for the sinfo pipeline can be downloaded as a PDF file using the following URL: - **ftp://ftp.eso.org/pub/dfs/pipelines/sinfoni/sinfo-pipeline-manual-19.0.pdf** An overview over the existing ESO pipelines can be found on the web page **http://www.eso.org/sci/software/pipelines/**. Basic documentation about the EsoRex program can be found at the esorex (1) man page. It is possible to call the pipelines from python using the python-cpl package. See **http://packages.python.org/python-cpl/index.html** for further information.
