Notes. αapp and αabs refer to the intercepts of the labelled relations in apparent and absolute magnitudes, respectively. “M06” refers to Matsunaga et al. (2006), “M11” refers to Matsunaga et al. (2011), “R15” refers to Ripepi et al. (2015), “B17” refers to Bhardwaj et al. (2017a), “I18” refers to Iwanek et al. (2018), “W22” refers to Wielgórski et al. (2022), “TW” (grey line) refers to this work. “#star” indicates the number of stars used in the fit.
