Required Data¶
This page gives an overview of what data is required to run the pipeline along with how to obtain the data.
Acquiring ASKAP Data¶
Note: VAST Data Releases
If you are a member of the VAST collaboration you will have access to the VAST data release which contains the data for the VAST Pilot Survey. Refer to the VAST wiki for more details.
Data produced by the ASKAP telescope can be accessed by using The CSIRO ASKAP Science Data Archive (CASDA). CASDA provides a web form for users to search for the data they are interested in and request for the data to be staged for download. Note that a form of account or registration is required to download image cube products.
All data products from CASDA should be compatible without any modifications. Please report an issue if you find this to not be the case.
Tip: CASDA Data Products
Descriptions of the data products available on CASDA can be found on this page.
Pipeline Required Data¶
Warning: Correcting Data
Currently, the pipeline does not contain any processes to correct the data as it is ingested by the pipeline. For example, if corrections to the flux or positions need to be applied, these should be done to the data directly before they are processed by the pipeline.
If an image has been previously ingested before corrections were applied, the filename of the corrected image must be changed. Doing so will make the pipeline see the corrected image as a new image and reingest the corrected data.
A pipeline run requires a minimum of two ASKAP observational images to process. For each image, the following table provides a summary of the files that are required.
| Data | File Type | Description |
|---|---|---|
| Primary image | .fits | The primary, Stokes I, taylor 0, image of the observation. |
| Component Catalogue | .xml, .csv, .txt | The component source catalogue produced by the source finder selavy from the primary image. |
| Noise map of primary image | .fits | The noise (or rms) map produced by the source finder selavy from the primary image. |
| Background map of primary image (optional) | .fits | The background (or mean) map produced by the source finder selavy from the primary image. The background image is only required when source monitoring is enabled. |
Refer to the respective sections on this page for more details on these inputs.
Image File¶
This is the primary image file produced by the ASKAP pipeline. The pipeline requires the Stokes I, total intensity (taylor 0) image file. It is also recommended to use the convolved final image, where each of the 36 individual beams have been convolved to a common resolution prior to the creation of the combined mosaic of the field. These files are denoted by a .conv in the file name.
Must be in the FITS file format.
Example CASDA Filename
image.i.SB25597.cont.taylor.0.restored.conv.fits
Component Catalogues¶
Currently, the pipeline does not contain any source finding capabilities so the source catalogue must be provided. In particular, the pipeline requires the continuum component catalogue produced by the selavy source finder.
The files can be one of three formats:
XMLThe VOTable XML format of the selavy components catalogue. Provided by CASDA. Must have a file extension of.xml.CSVThe csv format of the selavy components catalogue. Provided by CASDA. Must have a file extension of.csv.TXT'Fixed-width' formatted output produced by the selavy source finder directly. These are not available through CASDA. Must have a file extension of.txt.
Example CASDA Filenames
selavy-image.i.SB25597.cont.taylor.0.restored.conv.components.xml
AS107_Continuum_Component_Catalogue_25597_3792.csv
Note that CASDA does not provide the fixed width text format selavy output.

Noise Image File¶
This is the noise map that is created from the primary image file during source finding by selavy.
Must be in the FITS file format.
Example CASDA Filename
noiseMap.image.i.SB25600.cont.taylor.0.restored.conv.fits
Background Image File¶
This is the mean map that is created from the primary image file during source finding by selavy. The background image files are only required when source monitoring is enabled in the pipeline run.
Must be in the FITS file format.
Example CASDA Filename
meanMap.image.i.SB25600.cont.taylor.0.restored.conv.fits
Data Location¶
Data should be placed in the directories denoted by RAW_IMAGE_DIR and HOME_DATA_DIR in the pipeline configuration. The HOME_DATA_DIR is designed to allow users to upload their own data to their home directory on the system where the pipeline is installed. By default, the HOME_DATA_DIR is set to scan the directory called vast-pipeline-extra-data in the users home area.
Refer to the Pipeline Configuration section for more information.
