通过创建观测良好的文献核心坍缩超新星（CCSNe）的光谱能量分布，我们提出了校正转换光学光变曲线全测热光变曲线。这些修正采用抛物线拟合光学颜色的形式，其中B − I和g − r作为示例性拟合，同时也给出了拟合其他颜色的参数。我们发现，在大多数情况下，所有类型的CCSNe中，颜色校正的演变是非常均匀的，并且还分别适合剥离信封和II型SNe。一个单独的适合，适当的SNe表现出强烈的排放，由于冷却冲击后爆发，提出。这种方法将使CCSNe的测辐射热光变曲线的创建均匀化，其中观测不能约束发射通量----这对于当前和未来的SN调查特别重要，因为绝大多数事件的典型后续行动将仅发生在光学窗口中，从而导致涉及测辐射热光变曲线的建模的一致比较。SNe 1987 A和2009 jf使用这里提出的方法的测试情况下，和测辐射热光变曲线恢复在每种情况下具有良好的精度。关键词：超新星：一般。
Through the creation of spectral energy distributions for well-observed literature core-collapse supernovae (CCSNe), we present corrections to transform optical light curves to full bolometric light curves. These corrections take the form of parabolic fits to optical colours, with B − I and g − r presented as exemplary fits, while parameters for fits to other colours are also given. We find evolution of the corrections with colour to be extremely homogeneous across CCSNe of all types in the majority of cases, and also present fits for stripped-envelope and Type II SNe separately. A separate fit, appropriate for SNe exhibiting strong emission due to ooling after shock breakout, is presented. Such a method will homogenize the creation of bolometric light curves for CCSNe where observations cannot constrain the emitted flux – of particular importance for current and future SN surveys where typical follow-up of the vast majority of events will occur only in the optical window, resulting in consistent comparisons of modelling involving bolometric light curves. Test cases for SNe 1987A and 2009jf using the method presented here are shown, and the bolometric light curves are recovered with excellent accuracy in each case. Key words: Supernovae: general.
