Light and velocity curves of blue stragglers – continuation of Fig. 3. A single spot 2% hotter than the photosphere was placed on the primary of V20 in order to qualitatively account for the asymmetry of the light curve (just for illustrative purposes; it was not included while analyzing the data). Parameters of the fits for NV400 and V20 are given in Tables 8 and 11 in the rows indicated with an asterisk. No fit is possible for V240, because the velocity amplitude is smaller than the observational errors.
