Notes.

^(a)

R1 = Table 1 from Rodríguez et al. (2023), B10 = Table 10 from Bianco et al. (2014), and “–” means no conversion is needed. See Section 3 for details.

^(b)

Converted from t_{g_max}.

^(c)

Converted from t_{B_max}.

^(d)

An additional systematic uncertainty of ∼1.3 days, resulting from the conversion between B-band and V-band, is not included in the reported uncertainty above.
