Table B.1.

Observed and derived parameters for the primaries in the SB1 sample, where vc is the synchronous velocity as defined by equation 1, with log fc and log fp being the inferred ratios of v sin i to vc for the cases of circular and eccentric orbits respectively. The column headed ‘An’ denotes the method used to derive the atmospheric parameters as discussed in subsection 3.2.
