template track in the time-stretched color-magnitude diagram, we regard that our set of $f_{\rm s}$, $E(B-V)$, $(m-M)_V$, and distance $d$ are reasonable.

Reddening and distance {#distance_comparison}
----------------------

In what follows, we use LV Vul, V1500 Cyg, V1668 Cyg, and V1974 Cyg as template novae, because their distances and extinctions have been well determined. Figure \[distance\_reddening\_lv\_vul\_v1500\_cyg\_v1668\_cyg\_v1974\_cyg\] shows the distance-reddening relations toward the four template novae, (a) LV Vul, (b) V1500 Cyg, (c) V1668 Cyg, and (d) V1974 Cyg. We have already analyzed them in our previous papers [e.g., @hac16k; @hac16kb], but here we reanalyze them because new distance-reddening relations are recently available [e.g., @gre18; @chen18]. To summarize, we use five results: (1) @mar06 published a three-dimensional (3D) extinction map of our Galaxy. The range is $-100\fdg0 \le l \le 100\fdg0$ and $-10\fdg0 \le b \le +10\fdg0$ and the resolution of grids is $\Delta l=0\fdg25$ and $\Delta b=0\fdg25$, where $(l, b)$ is the galactic coordinates. (2) @sal14 presented a 3D reddening map with the region of $30\arcdeg \le l < 215\arcdeg$ and $|b|<5\arcdeg$. Their data are based on the INT Photometric H-Alpha Survey (IPHAS) photometry. (3) @gre15 published a 3D reddening map with a wider range of three quarters of the sky
