ALMA Imaging Pipeline Reprocessing Tool

Cycle Compatibility and New Tool

In Cycle 9, a new nomenclature was adopted for measurement sets within the ALMA pipeline: uid*targets.ms for the continuum + line (non-continuum-subtracted) target-only data, and uid*targets_line.ms to reference the continuum subtracted data. Data restored with a scriptForPI.py from prior to Cycle 9 will have an incompatible uid*target.ms format, and must be modified to uid*targets.ms to work with the scripts in this guide.

Additionally, to improve the ease of imaging pipeline reprocessing, a new tool has been developed to streamline the methods detailed below. The documentation for this tool can be found here: .

About This Guide

This guide describes some examples for perfecting the interferometric imaging products from the ALMA Cycle 9 Pipeline. If your data were manually imaged by ALMA, you should instead consult the scriptForImaging.py delivered with your data.

The Section Restore Pipeline Calibration and Prepare for Re-imaging describes the first steps to do. After that, the individual sections are self-contained (and they typically assume the "Restore" has been performed). It illustrates how to completely re-run the pipeline from beginning to end in order to reproduce the pipeline run done at your ARC.

Additional documentation on the Cycle 9 pipeline can be found in the Pipeline User's Guide which can also be found at the ALMA Science Portal. The User's guide describes how to obtain the ALMA Pipeline, how to use it to calibrate and image ALMA interferometric (IF) and single-dish (SD) data, and a description of the Pipeline WebLog.

Note that the scripts described in this guide have only been tested in Linux.
