IRAM NOEMA Observation Log: Millimeter-Wave Interferometer Data

IRAM NOEMA observation log summarizes observations from the Northern Extended Millimeter Array, a French-German-Spanish radio astronomy facility. The table was originally ingested by NASA HEASARC in August 2017 and last updated in September 2020. It is based on tables obtained from the CDS and provides a service record for the NOEMA interferometer, which evolved from a three-antenna array in 1988 to an eight-antenna array by 2016.

Use Cases

• Analyzing observation scheduling and telescope usage patterns based on the log entries.
• Studying the evolution of the interferometer's capabilities based on the described baseline extensions and antenna additions.
• Correlating observational targets with scientific outcomes in millimeter-wave astronomy.

Strengths

• Managed by a major international collaboration (IRAM, founded 1979) involving CNRS, MPG, and IGN.
• Log covers the evolution of the facility from 1988 to 2016, including baseline extensions from 288 to 760 meters.
• Hosted and maintained by NASA HEASARC, providing institutional credibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last updated in September 2020; freshness should be verified for current research.
