Products

The ARKS programme has produced a series of data products and analysis scripts that are publicly available for the benefit of the wider community. Most products can be found in the ARKS Dataverse hosted in the Harvard Dataverse. These products include:

• Data reduction scripts: It includes CASA scripts to reduce and correct the data following the same procedure as described in ARKS I by Marino et al.

• Dust continuum data: It includes dust continuum visibilities (MS files and visibility tables), clean images, and a summary table that contains information about each system’s star and disc. The methods and data are described in ARKS I by Marino et al.

• Dust radial profiles: It includes dust radial profiles obtained from the clean images, parametric methods, and non-parametric methods, and tables describing the location of rings and gaps in the 24 discs. The methods and results are described in ARKS II by Han et al.

• Dust vertical distribution: It includes a table with the best-fit parameters of those discs that are vertically resolved and fitted using a parametric table, and a table with the scale heights derived using parametric and non-parametric methods. The methods and results are described in ARKS III by Zawadzki et al.

• CO gas data: It includes 12CO and 13CO MS files, Clean cubes, moment maps, and radial profiles for the 6 systems that are gas-rich. For the 18 gas-free systems, these include the MS files and image cubes. The methods and data are described in ARKS IV by Mac Manamon et al.

• CO imaging pipeline: It includes the scripts used to image the CO gas of the 18 discs observed as part of ARKS, as described in ARKS IV by Mac Manamon et al.

• Scattered light data: It includes scattered light images and models found to best fit the observations. It also provides the scattering phase functions that best match the observations. The methods and data are described in ARKS V by Milli et al.

• Asymmetry analysis scripts and additional data: It includes scripts used to search for asymmetries and non-standard images used specifically to assess the presence of asymmetries in some discs. The methods and data are described in ARKS VI by Lovell. et al.

• Hydrodynamic simulations’ products: It includes data and simulation products of hydrodynamical simulations used to explain the dust distribution in HD 121617. It is intended to help readers inspect key measurements, reproduce core figures, and help replicate the analysis in the paper. The methods and data are described in ARKS IX by Weber et al.
