ZTF DR3 RR Lyrae Variable Star Catalog

A catalog of RR Lyrae variable stars identified from the Zwicky Transient Facility Data Release 3. The catalog was published by Kuan‐Wei Huang of Carnegie Mellon University alongside the journal paper 'Identifying RR Lyrae in the ZTF DR3 dataset'. The specific number of stars, time coverage, and data volume are not detailed in the provided metadata.

Use Cases

• Studying the properties and distribution of RR Lyrae stars based on ZTF light curves.
• Calibrating distance measurements in the Milky Way using RR Lyrae as standard candles.
• Analyzing stellar variability and pulsation characteristics from time-series photometry.
• Training or validating machine learning models for automated variable star classification.

Strengths

• Catalog is associated with a peer-reviewed journal publication, suggesting scientific validation.
• Data originates from the Zwicky Transient Facility, a major astronomical survey.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
