Notes.Columns: name, HD number, spectral type, distance, V and K magnitudes, rotational velocity, estimated limb-darkened diameter, apparent oblateness, measured limb-darkened diameter (if available), and age. The 1σ errors are given in superscript. The V magnitudes are taken from Simbad or Kharchenko & Roeser (2009), and the vsini from the catalogues of Royer et al. (2007), Valenti & Fischer (2005), Reiners (2006) and Martínez-Arnáiz et al. (2010), except in the cases of kap CrB (from Johnson et al. 2008), alf Lyr (from Monnier et al. 2012), alf Aql (from Monnier et al. 2007) and alf Cep (from Zhao et al. 2009).

^(a)

Geometric mean of the minor and major axes of the projected elliptical photosphere.

^(b)

References are given for the K-band magnitude, the measured diameter and the age, using the notations here below.
