Filtered Exoplanet Data with Mass and Radius Quality Flags

Confirmed exoplanet records from the NASA Exoplanet Archive filtered for default parameter sets as of March 2026. Created by Aradhya Haldikar, the dataset includes physical measurements and derived quality flags for mass and radius uncertainties. It focuses on objects with high-precision measurements suitable for demographic analysis.

Use Cases

• Demographic analysis of exoplanet populations using mass_quality and rade_quality filters
• Statistical modeling of mass-radius relationships using pl_masse and pl_rade
• Uncertainty quantification studies using mass_frac_err and rade_frac_err

Strengths

• Includes derived boolean flags (mass_quality, rade_quality) for rapid filtering of high-precision data
• Standardized on default_flag=1 to ensure one unique record per confirmed planet
• Provides pre-calculated fractional uncertainty columns (mass_frac_err, rade_frac_err)

Limitations

• Planets without reported errors are assigned False for quality flags regardless of actual measurement precision
• Restricted to confirmed planets, excluding the wider pool of exoplanet candidates
