NuSTAR As-Flown Timeline: Satellite Observation Summary

The NuSTAR As-Flown Timeline (NUAFTL) database table records the observation history of the Nuclear Spectroscopic Telescope Array (NuSTAR) hard X-ray observatory. NuSTAR observes the sky in the high energy X-ray (3 - 79 keV) region of the electromagnetic spectrum. This HEASARC database table is updated automatically within a day or so of each observation's completion and is a service provided by NASA HEASARC.

Use Cases

• Analyzing the temporal coverage and target selection of the NuSTAR mission based on the observation timeline.
• Correlating NuSTAR observation periods with data from other telescopes for multi-wavelength studies.
• Validating satellite operational schedules and data acquisition logs based on the as-flown record.
• Researching high-energy X-ray source variability using the sequence and timing of observations.

Strengths

• Data is updated automatically within a day or so of each observation's completion, suggesting near-real-time availability.
• Originates from the authoritative NASA HEASARC service, indicating institutional reliability.
• Focuses on a specific, high-energy (3-79 keV) region of the electromagnetic spectrum.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
