A CALIBRATION OF THE uυbyβ PHOTOMETRIC SYSTEM IN TERMS OF TEMPERATURE AND GRAVITY

As an aid to the systematic study of photometric classification, this paper presents a calibration of the uυbyβ system expressed as contour lines for the indices (b — y), m₁, c₁, and β on the (log Teff, log g) plane. The calibration extends to B, A, and early F supergiants. A comparison with part of...

Summary:As an aid to the systematic study of photometric classification, this paper presents a calibration of the uυbyβ system expressed as contour lines for the indices (b — y), m₁, c₁, and β on the (log Teff, log g) plane. The calibration extends to B, A, and early F supergiants. A comparison with part of the MK classification is also shown, and further applications are discussed.
