1. ^ The calculation for absolute magnitude applied here is ${\displaystyle {\begin{smallmatrix}M=m-5((\log _{10}{D_{L}})-1)\!\,\end{smallmatrix}}}$, where ${\displaystyle {\begin{smallmatrix}m\!\,\end{smallmatrix}}}$ is the apparent magnitude and ${\displaystyle {\begin{smallmatrix}D_{L}\!\,\end{smallmatrix}}}$ is the luminosity distance in parsecs.
