Аннотация:We have compared the results of multicolor U BV R and H alpha photometry for 169 young star-formation complexes in five galaxies using a grid of evolutionary models for young star clusters. The ages and interstellar absorptions are estimated for 102 star-formation complexes with the standard uncertainties sigma(t) = 0.30 dex and sigma(AV) = 0.45(m). The accuracies of these parameters were verified using numerical simulations.
