Some Comments about Magnitude and Redshift

The bolometric (apparent) magnitude:

\begin{eqnarray*}m &=& -2.5\log_{10}\left(\frac{S}{2.52}\times10^{-5}\,\frac{\te...
...rm{Constant} \\
&=& 5.0\log_{10} R + \textrm{Another Constant}
\end{eqnarray*}


If R = z / H0 then

\begin{eqnarray*}m &=& 5.0 \log_{10} R + \textrm{Constant} \\
&=& 5.0 \log_{10...
...10} z + \textrm{Yet another Constant that has $H_0$\space in it}
\end{eqnarray*}
