Abstract
The relationship between visual surface brightness parameter Fυ and the (V–R)0 colour index is improved by adding 40 new stars to the 52 stars used in the previous calibration. Explicit corrections for limb-darkening effects on the observed angular diameters are introduced. New BVRI photometry is reported for 39 stars used in the calibration. The new calibration strengthens the previous assertion that the $$F_V-(V-R)_0$$ relation is independent of luminosity class and applicable to all spectral types O4–M8, S, and C.
