| Abstract: | The results of a morphological classification of 580 galaxies with a UV excess, included in the lists in M. A. Kazarian, Astrofizika,15, 5 (1979); ibid.,15, 193 (1979); M. A. Kazarian and É. S. Kazarian, ibid.,16, 17 (1980); ibid.,18, 512 (1982); ibid.,19, 213 (1983)], are presented. For this we have developed a set of symbols, using the types E, S, and Ir introduced by Hubble, as well as symbols introduced by other authors and us. This set enabled us to make the morphological classification. Direct photographs obtained on the 2.6-m and 6-m telescopes were used to classify 141 of the galaxies (over 24%), while Palomar Atlas charts were used for the remaining 439 galaxies. These galaxies were divided into two groups based on classification conditions, and data on each group are given in Tables 1 and 2, respectively. The results for each group, given in Table 3, show that with the transition from early types, such as C and E, to later types, such as S and Ir, the relative number of galaxies going into one group (Table 1), in which the classification was based on direct photographs, increases in comparison with the number going into the other group (Table 2).Translated from Astrofizika, Vol. 39, No. 3, pp. 431–439, July–September, 1996. |
