Preserving the Past, Enabling the Future

The MeerKAT Archive serves as an index of world-class scientific observation. In the first instance, the archive interface is the portal through which most MeerKAT scientific users access the telescope data to perform relevant reduction, analysis and scientific discoveries leading to publication. In the longer term, the archive is intended to preserve data that will continue to be valuable even as more sensitive instruments come online. The discoveries made with MeerKAT – from detailed maps of the Milky Way’s heart to the detection of never-before-seen cosmic structures – represent an essential foundation for future studies.

It is expected that later this decade MeerKAT will be incorporated into the SKA-Mid telescope. Because it can take several years to convert data into science, and because of the inherent long-term legacy value of a well-curated high-quality data set, we expect to continue supporting the MeerKAT Archive well into the 2030s.

A Functional, User-Driven Interface

The SARAO Archive team have worked diligently to release this updated archive UI with a focus on usability and accessibility. Our goal is to ensure that every user, from professional astronomers to curious explorers, can easily interact with the wealth of data captured by the MeerKAT telescope.

We’ve revamped the interface and introduced new features to improve usability. Some of the key updates include:

• User-level data transfers, providing better visibility into triggered and requested actions
• Multiple measurement sets per capture block, with an improved interface for specifying arguments and expanded mvftoms parameter support.
• Direct access to some USE (User Supplied Equipment)-generated data from SARAO’s servers via the portal (interim dependence on OzStar for retrieval of pulsar timing data no longer required).
• Bulk downloads of selected products and measurement sets are now supported. Resilient scripts are provided to streamline the transfer of very large files, even across network interruptions, server restarts, and other disruptions.
• More compact information displays and expanded filtering options for capture blocks and transfers (including the state of product transfers from site).
• Fully API-driven for querying, processing, and integrating our Archive metadata into programmatic workflows.

We welcome feedback on existing and potential features, as we strive to support diverse use cases and maximize the impact of this rich data repository. Your input will help shape future enhancements, ensuring that the MeerKAT Archive remains an invaluable resource for years to come.

Looking Back and Moving Forward

As South Africa’s contributions to science and engineering continue to grow, the MeerKAT Archive marks how far we have come. It reflects not only the achievements of the past decade but also the bright future ahead – one where South African-led innovation continues to drive astronomy forward on a global scale.
