Notes. The function Z5 corrected for contamination bias is obtained by setting r0 = r1 = 0. The table gives qjk(G) and rk (G) at the values of G in the first column. For other values of G, linear interpolation should be used. A dash (–) indicates that the coefficient should be ignored (taken as zero). Units are μas (for q0k), μas μm (for q1k), and μas dex−1 (for rk).
