↑ For apparent magnitude m and parallax π, the absolute magnitude Mv is given by: M v = m + 5 ( log 10 π + 1 ) = 0.03 + 5 ( log 10 0.12893 + 1 ) = 0.58 {\displaystyle {\begin{smallmatrix}M_{v}\ =\ m+5(\log _{10}{\pi }+1)\ =\ 0.03+5(\log _{10}{0.12893}+1)\ =\ 0.58\end{smallmatrix}}} See: Tayler, Roger John (1994).
