Results on the gr-band light curves of the five classified SN-like transients. In each panel, solid circles plus error bars in blue and in red represent the data points in g-band and r-band. Solid line and dashed lines in blue and in red show the best fitting results and corresponding 1RMS scatters to the g-band and r-band light curves. Vertical solid and dashed lines in blue and in red mark the positions of the maximum and half maximum of the best fitting results to the g-band and to the r-band light curves. The determined R_1/2, rd are listed in blue and red characters through the best fitting results to the g-band and r-band light curves.
