Table 4: Illustration of results underlying the mean radial velocities $v_{\rm rad}$ in Table 3 (cf. Eq. (3)). The star HD 24970 (A0) was observed N = 3 times and has $N_{\rm s} = 5$ suitable standard stars, giving rise to 5 radial velocities per exposure. These values are listed (in km s^-1), together with the spectral classifications and distances d and weights w (see Eqs. (1) and (4)) of the standard stars. The distance-weighted mean radial velocities with their errors are listed in the final column (in km s^-1). Systematic differences between columns in this table can be due to template mismatch and/or incorrect literature radial velocities; in general, systematic differences between lines in this table can be due to random errors (statistics), instrumental shifts, and/or multiplicity (not likely in this specific case).
