Peak magnitudedecline relation and the peak magnitudecolor evolution relation for 10 stripped-envelope CCSN. Absolute magnitudes in the B band are plotted vs. Δm₁₀(B), Δm₂₀(B), and Δm₃₀(B), analogous to the SLSN sample in Figure 5. The Δ(B − V)₃₀ measures the color evolution in B − V over 30 days. The data sources are as follows: the type Ic SN 2007gr (Valenti et al. 2008b; Hunter et al. 2009), 1998bw (Galama et al. 1998; McKenzie & Schaefer 1999; Sollerman et al. 2000; Patat et al. 2001), 2003jd (Valenti et al. 2008a), 2008D (Mazzali et al. 2008; Soderberg et al. 2008; Modjaz et al. 2009), 1994I (Richmond et al. 1996), 2002ap (Pandey et al. 2003; Foley et al. 2003; Yoshii et al. 2003; Tomita et al. 2006), and 2006aj (Campana et al. 2006; Cobb et al. 2006; Mirabal et al. 2006; Pian et al. 2006; Sollerman et al. 2006); the type Ib SN 2007Y (Stritzinger et al. 2009), 2009jf (Valenti et al. 2011), and the type IIb SN 2008ax (Pastorello et al. 2008).
