Pipeline information

• The pipeline produces a calibrated data set (calibrated continuum without self-calibration) and diagnostic plots (visibilities, tables, flags, etc).
• The pipeline can be executed several times, so it is easy to repeat the whole calibration or individual steps. Every step will remove any previous file (MS, tables, etc) before running again to re-generate them cleanly, so no need to delete any file or table in the process.
• The steps are sequential, so if you repeat any one you should run the later ones as well.
• Open ./weblog/index.html in your web browser to see the weblog outputs
• Calibration tables are stored in ./weblog/calib, and preliminary images in ./weblog/images
• The calibrated data (MS file), calibration tables, plots and the content of the weblog can be downloaded from the link in the "Download data" tab.
• More info: e-MERLIN Pipeline Github
  

Easy way to re-run the pipeline

There are two main blocks: pre-processing and calibration. Most probably you will only need to repeat the calibration part. Recommended course of action:

• Identify changes you want to implement in the data reduction, like changing calibration parameters or adding manual flags.
• Identify changes you want to implement in the data reduction, like changing calibration parameters or adding manual flags.
• Add or edit file manual_avg.flags with your flag commands (follow the CASA syntax)
• Edit the file inputs.ini if you need to change the sources used or they intend
• Edit the file default_params.json if you need to change parameter used by the pipeline
• Run the calibration block of the pipeline with the command:

   casa -c ./eMERLIN_CASA_pipeline/eMERLIN_CASA_pipeline.py -r calibration

• Use the same CASA version and pipeline version as previous runs (check tab Pipeline info in the weblog).

The weblog will be updated after each step so you can track what is happening. The file eMCP.log contains details of what the pipeline is doing and some parameters used. All details about the pipeline can be found in e-MERLIN Pipeline Github

Acknowledging e-MERLIN and the pipeline

Papers that result from e-MERLIN observations should carry the standard acknowledgement: "e-MERLIN is a National Facility operated by the University of Manchester at Jodrell Bank Observatory on behalf of STFC, part of UK Research and Innovation."

Please cite the e-MERLIN CASA Pipeline (eMCP) in any resulting publications of this data: eMCP ADS Link

Papers that are funded by the EC* should also carry the following acknowledgement(s): "This project has received funding from the European Union?s Horizon 2020 research and innovation programme under grant agreement No 101004719."

"This [infrastructure] participates in a project that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 101004719."
