IRAM Plateau de Bure Interferometer Observation Log, 1990-2017

IRAM, founded in 1979, studies cold matter in the universe using millimeter-wave observatories. This log summarizes observations from the six-antenna Plateau de Bure Interferometer in France between December 1, 1990, and March 31, 2017. The table was last updated by NASA HEASARC in July 2019.

Use Cases

• Analyzing observation scheduling and telescope usage patterns based on the recorded log period.
• Studying the temporal distribution of astronomical targets based on the 27-year observation span.
• Investigating the impact of instrument upgrades, like receiver installation, on observational data gaps.

Strengths

• Covers a 27-year observation period from 1990 to 2017.
• Documents specific gaps in data collection (e.g., 1999-2000, 2006-2007) for transparency.
• Maintained by NASA HEASARC and updated as of July 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific observatory's operational schedule.
