Upper panels: classification of DDF light curves and lower panels: classification of WFD light curves. Left panels: accuracy as a function of the total number of observations on different dates for all bands. Middle panels: accuracy as a function of S/N, which is computed as the maximum S/N from all bands. Right panels: accuracy as a function of peak magnitude, which corresponds to the maximum value of peak magnitude from all bands. For each case the distribution of the training database is represented in light green and that of the test database in gray.
