Overview
The NRAO Archive contains data from as far back as 1976, and currently contains just over 3 petabytes of information. Preserving this data and providing tools for the efficient utilization of the data products by the full multi-messenger community is a key responsibility of the DMS department. Starting in 2023, DMS will launch a new project to expand the use of the NRAO Archive as a Research Instrument. This project will focus on user specified reprocessing, interoperability with other science archives, and increasing the supported type of projects. We expect this project to extend at least into 2024 and perhaps to 2025.
Key Goals
- Scriptability of the archive query interface via VO-compliant Table Access Protocol (TAP).
- Download improvements (inclusion of wget commands to retrieve data).
- Search improvements.
- Position search fixes (see Known Issues below).
- Search based on integration time.
- Scanlist improvements
- VLA-specific
- Metadata display improvements (i.e., scan list, sources, frequency setup(s), total integration times).
- VLBA-specific
- Completion of VLBA data collection: Fixing corrupted Mark IV files, and adding a few missing GMVA, HSA, and Global VLBI data.
- Downloading large numbers (>500) of correlation files for VLBA projects in bulk via the 'Select All' option.
- Fixing the missing or incomplete metadata of some VLBA+EVLA (i.e. +Y1, +Y27) projects, without which download is impossible.
The goal of this page is to compile both issues with the New Archive (AAT) and features the Legacy Archive (LA) has but not the AAT. The issues posted will be reviewed by John Tobin and Anna Kapinska (archive sub-system scientists) for submission as Jira tickets or submission of a requested development project for SSA planning. See the example for an issue posting below, we ask that whomever records an issue put their name and date along side it such that we can reach out if further information is needed.
