Description

The KVN pipeline for maser is a set of python scripts for the data reduction of the multi-frequency KVN observations toward the stellar maser sources. The KVN pipeline for maser can deal with only the single polarization observations.

Required packages

  1. AIPS
  2. Obit and ParselTongue
    • Installation instructions for AIPS can be found here.
    • Installation instructions for Obit and ParselTongue can be found here.

How to install and run

1. Extract kvnpipe_line.zip .

  • KVN pipeline for maser consists of seven files.
    • kvntask.py
    • crfuncs.py
    • p16sc04a.py
    • cploti.py
    • input.txt
    • fring.input
    • levs.txt

2. Copy the each file into the proper locations as belows.

  • Pipeline path (e.g. ~/pipeline)
    • ~/pipeline/kvntask.py
    • ~/pipeline/crfuncs.py
  • Work path (e.g. ~/reduction/p16sc04a)
    • ~/reduction/p16sc04a/p16sc04a.py
    • ~/reduction/p16sc04a/input.txt
    • ~/reduction/p16sc04a/fring.input
  • Result path (e.g. ~/reduction/p16sc04a/VY-CMA)
    • This directory is automatically created after the pipeline starts.
    • ~/reduction/p16sc04a/VY-CMA/cploti.py
    • ~/reduction/p16sc04a/VY-CMA/levs.txt
    • These two files should be copied to result path after the pipeline process is complete.

3. Edit your shell environment (e.g. ~/.bashrc)

  • Append export PYTHONPATH=“~/pipeline:$PYTHONPATH”

4. Edit input.txt and fring.input .

  • The contents of these files should meet the purpose of a specific observation.

5. Run script in work path.

  • cd ~/reduction/p16sc04a/
  • chmod u+x p16sc04a.py
 ./p16sc04a.py input.txt 

6. Plot the overlapped contour maps after the pipeline process is complete.

  • cd ~/reduction/p16sc04a/VY-CMA
  • Edit p16sc04a.py and input.txt .
 python cploti.txt
