Since 2017 the default CASA pipeline runs on VLA programs and VLA test observations. Successfully determined calibrator flux densities are automatically extracted and, to first order, presented as a spectral overview and a time series per source. |

Eligible archival continuum VLA observations during 1982-2005 were provisionally pipelined using AIPS and archived. Raw and calibrated calibrator and target source visibilities and images are available and may be useful for further processing or analysis. |

The array operator logs are being merged with the new e2e archive system, this lookup tool has been provided as a stopgap measure to tide us over until the work is done. The logs here are from October 2003 onwards, older logs can be found using the previous tool. |

All scientific data from NRAO telescopes are stored in an archive. The archive contains the raw data: GBT files in FITS binary table format, export files from the old VLA, ASDM formatted files from the current VLA, and FITS-IDI files from the VLBA, including correlated data from any non-VLBA telescopes that have been used in conjunction with the VLBA. These data are reserved for the exclusive use of the observing team for a fixed period after the last observing session of a project has been completed. This proprietary period is 12 months following the last observation. |
