ALMA Pipeline Heuristics Release R1

At this time the ALMA Pipeline Group is pleased to announce the first internal release of the ALMA Pipeline Heuristics scripts to the ALMA staff. The heuristics scripts will be used by the ALMA Pipeline System to reduce data taken in standard observing modes and to provide science data products that can be used for further analysis. The current scripts support single dish, single field interferometry, and pointed mosaic observations. The output of the scripts has been tested by external users during several user tests. See

http://almasw.hq.eso.org/almasw/bin/view/PIPELINE/PipelineHeuristics

for test results.

The single dish scripts are currently able to handle ALMA data in ASDM format and data from other observatories in ASAP format. To date the interferometry scripts have been developed using VLA and IRAM PdB and some SMA data. We have begun to reduce early ALMA interferometry data sets, but this capability is still very experimental and requires special scripts.

The files in this directory provide release R1 of the ALMA pipeline heuristics scripts and their Casa task interfaces:

• PIPELINE-R1.tgz:

  • The actual pipeline heuristics scripts. Unpack into $HOME/alma-heuristics via
    
    mkdir $HOME/alma-heuristics
    cd $HOME/alma-heuristics
    tar xzf $HOME/PIPELINE-R1.tgz
    
    (assuming you downloaded this tar ball to your home directory). Prepare tasks as follows:
    
    cd HOME/alma-heuristics/PIPELINE-R1/Heuristics/src/heuristics/SDPipelineTaskInterface
    buildmytasks # Needs Casa 3.0.2 or higher to be installed
    cd HOME/alma-heuristics/PIPELINE-R1/Heuristics/src/heuristics/SFIPipelineTaskInterface
    buildmytasks # Needs Casa 3.0.2 or higher to be installed

• reduce_sfi:

  • ALMA pipeline regression task script for VLA and
    Plateau de Bure single field data. Edit and run in
    Casa with "execfile('reduce_sfi').
    

• reduce_mosaic:

  • ALMA pipeline regression task script for VLA and
    Plateau de Bure mosaic data. Edit and run in
    Casa with "execfile('reduce_mosaic').
    

• reduce_sd:

  • ALMA pipeline regression task script for single
    dish data in ASDM or ASAP format. Edit and run in
    Casa with "execfile('reduce_sd").
    

• add_source_type:

  • Casa script to add the source type column. Edit
    according to your needs and run in casapy by
    typing "execfile('add_source_type')".
    

• README / README.html:

  • This document.
    

• rawdata/*/*.tar.gz:

  • Sample heuristics regression data (interferometry data
    with the SOURCE_TYPE column already set):
    
    sfi/h099-i207.raw.tar.gz: PdB SFI data
    sfi/vla_g28-B.raw.tar.gz: VLA SFI data
    mosaic/orion-3.6cm-mos.tar.gz: VLA mosaic data
    sd/m16-co43-v2.ASAP.tgz: APEX single dish data
    

The scripts expect MeasurementSet data with an additional SOURCE_TYPE column in the FIELD table. The ALMA pipeline test datasets do have this column. Other datasets need to be edited to add it. This column tells the script the source intent (SOURCE, FLUX, BANDPASS, GAIN calibrator or NONE).

This release has been developed and tested for Casa 3.0.2 build 11761. There are still known limitations in the heuristics scripts and some efficiency and resource usage issues that will be addressed in future releases.
