This archive tool provides access to VLA (historical and post-upgrade), ALMA (Cycles 1 and higher), VLBA, and significant fraction of GBT data. Users seeking GBT data not found here should submit a science help desk ticket.
Users seeking ALMA Cycle 0 and/or the full assortment of ALMA image and calibration products should use the ALMA Science Archive (https://almascience.nrao.edu/asax/).
For questions, please contact the science help desk (https://help.nrao.edu) and select the "Data Products" topic.
Additional features this release include:
Missing Scans/BDFs should now be flagged on ingestion
Improved display of archive ingestion/observation issues
Missing Scans/BDFs warnings should now be highlighted in yellow
Improved Scan Lists
Introduction of pagination
Introduction of Spectral Window data for EVLA, ALMA, VLBA, and GMVA
Various display improvements and corrections for previously held observation data
Please Note: support of these features will require extensive data reingestion.
QA Notes for newly ingested non-VLASS Calibrations are available from the Archive
QA Notes for newly ingested non-VLASS Images are available from the Archive
X-band will no longer be listed as an observation band if it was only used for pointing for newly ingested EVLA data
The Science Helpdesk is now accessible from the Archive
Curator: NRAO Archive Reingestion System
VLBI Ingestion Support
VLBA/GMVA file ingestion has been standardized to use the manifest driven system in use for other instruments
VLBA/GMVA file ingestion will be removed from the Legacy Archive and current AAT/PPI services
VLBA/GMVA ingestion is now controlled by AAT/WS via StackStorm
this includes:
- directory monitoring for the difx area
- directory renaming to reflect ingestion status
- Workspaces HTCondor based ingestion workflow implementation for VLBA, GMVA and Mark4 data types.
