The structure in the Virgo Cluster is studied on the basis of fractal structure analysis. The numbers of galaxies used are about two hundreds in this analysis in the area of 12h to 13h and 0° to 20° of right ascension and declination respectively. We get a result of the fractal dimension of 1.98±0.23 as preliminary result.

It happens frequently that the observational data is not complete but missing partly by various reasons. A preliminary study for supplementing adjusted values to such imperfect data based on Principal Component Analysis (PCA) is executed. IRAS 3 colors of mass-losing stars and their expanding velocity on the ground based observations are adopted for the experiment. One of these 4 data is eliminated for each star and the adjusted value is restored. The original data and the restored one are compared and the distribution of the restored errors is studied.本文データの一部は、CiNiiから複製したものである。
