absoluteMagnitudereadonly

Absolute visual magnitude as published, or null.

colorreadonly

Linear sRGB of a blackbody at temperature, brightest channel normalized.

colorIndexreadonly

Color index B−V as published, or null.

estimatedreadonly

True when the physical values above rest on a fallback rather than a measurement — no magnitude, or no classification. The system panel says so rather than presenting a guess as a reading.

massBasisreadonly

derived when the mass follows from the measurements, typical when it is a class-representative value because they do not determine it. A red giant's mass genuinely is not knowable from its light.

solarLuminositiesreadonly

Bolometric luminosity in solar units.
