Best fit of Eq. (1)(black solid line) to the r-band light curve (triangles) of SN 2006T normalized to its peak brightness. The three components of the analytic fit are shown: blue for the exponential rise, green for the Gaussian peak, and red for the linear decay. The corresponding terms in Eq. (1)are color-coded accordingly. The residuals between the fit and the photometry are plotted in the bottom panel, and in this case they never exceed 0.03 mag.
