Observations of ES-type double galaxies
Abstract
A table detailing UBV photometric observations of 30 ES-type double galaxies is presented. Integral magnitudes V and (B-V) and (U-B) color indices are determined. Observations are reduced to the standard UBV system and corrected for atmospheric extinction, galactic absorption, redshift, and inclination of both components to the line of sight. A considerable number of pairs are optical and there is a large difference between component color indices, caused by the combination of various morphological types in galaxy pairs.
