and color excess $E(B-V)$ to the target nova where we use the relation of $$\begin{aligned}
(m-M)_U = 4.75 E(B-V) + 5 \log (d/10~{\rm pc}),
\label{distance_modulus_ru}\end{aligned}$$ $$\begin{aligned}
(m-M)_B = 4.1 E(B-V) + 5 \log (d/10~{\rm pc}),
\label{distance_modulus_rb}\end{aligned}$$ $$\begin{aligned}
(m-M)_I = 1.5 E(B-V) + 5 \log (d/10~{\rm pc}),
\label{distance_modulus_ri}\end{aligned}$$ $$\begin{aligned}
(m-M)_K = 0.35 E(B-V) + 5 \log (d/10~{\rm pc}),
\label{distance_modulus_rk}\end{aligned}$$ and $A_U/ E(B-V)=4.75$, $A_B/E(B-V)=4.1$, $A_I/E(B-V)= 1.5$, and $A_K/E(B-V)= 0.35$ are taken from @rie85. We plot these relations of Equations (\[distance\_modulus\_ru\]), (\[distance\_modulus\_rb\]), (\[distance\_modulus\_rv\]), (\[distance\_modulus\_ri\]), and (\[distance\_modulus\_rk\]) in the reddening-distance plane. If these lines cross at the same point, this point gives correct values of reddening $E(B-V)$ and distance $d$ (for example, Figure \[distance\_reddening\_v574\_pup\_v679\_car\_v1369\_cen\_v5666\_sgr\](a)).\
[**6.**]{} Using $E(B-V)$, $(m-M)_V$, and $f_{\rm s}$ obtained in the above procedures, we plot the $(B-V)_0$-$M_V$ color-magnitude diagram and the $(B-V)_0$-$(M_V - 2.5\log f_{\rm s})$ time-stretched color-magnitude diagram of the target nova (for example, Figures \[hr\_diagram\_v574\_pup\_v679\_car\_v1369\_cen\_v5666\_sgr\_outburst\_mv\] and \[hr\_diagram\_v574\_pup\_v679\_car\_v1369\_cen\_v5666\_sgr\_outburst\], respectively). We derive the relation of $$\begin{aligned}
(m-M')_{V,\rm target} & \equiv & \left( m_V-(M_V - 
2.5\log f_{\rm s})\right)_{\rm target} \cr
&=& ((m-M)_V + \Delta V)_{\rm template},
\label{distance_modulus_general_dot}\end{aligned}$$ from Equations (\[time-stretching\_general\]) and (\[distance\_modulus\_general\_temp\]).\
